Titan Attacks! – get your Steam keys here

Ever wondered exactly what the Titans wanted revenge for? Not long ago, our esteemed friends from Titan attacked our peaceful planet, a battle which played out in our seminal shooter Titan Attacks – winner of’s Action Game of the Year!

Well obviously you must have soundly thrashed them. Why not relive history and show us how it was done – and in case you missed the news – now you can do it in recently updated crispy HD graphics!

Getting to the point 🙂 … Titan Attacks is now available on Steam for both Windows and Mac OS with over 40 new Steam achievements and online hiscore table!

… and to celebrate the launch, for one week only, it’s on special offer!

Alternatively, if you’d like to support us by buying direct, you can then activate a FREE Steam version, which means more pies and ale for us, and if you’ve already bought Titan Attacks no worries – we’ll give you a Steam key too.

New Droid Assault trailer, introducing Allicorn

A new trailer for the new year, with a spanking new tune by Allicorn, who is also our new programmery person!

Previously Allicorn did half of the droid sound effects and music for Droid Assault – his first task as full-time new programmery person is to make the Sandbox Mode add-on content for Revenge of the Titans, and hopefully he’ll have that ready for Easter or thereabouts. Over to Cas…

Allicorn and I have played pen-and-paper RPGs together once a week for the last five years. He is frighteningly clever but humble and helpful. When he’s not doing RPG gaming with me and our mutual friends, or coding for Puppygames, he’s also one of the administrators of Yog-Sothoth. I’d like to think there was some overlap in our clientele already.

Yeti Attack!

Wolcum Yole, Puppyfriends! As a special treat to all the boys and girls who have been good all year we have spent the last month working on completely free DLC for Revenge of the Titans!

All you need to do is make sure you install the latest v1.80.14 release (download the demo from our site here if you’re a Puppygames customer, or go to your Humble Indie Bundle download page, or just fire up Steam and it’ll update automatically). You’ll find that between 19th December and 8th January there’s a new game mode available – Yeti Attack! You get all the toys in the game, albeit in limited numbers, and you can even use disruptor towers safely! The objective is to survive for exactly 30 minutes of a constant stream of Hoff Yetis arriving from the north. The maps generated are completely random so there should even be some good replay value in there as well. Afterwards you will be treated to some amusing statistics.

New trailer for Titan Attacks v2, glitchy bits fixed, Revenge 1.80.13

To accompany the recent v2.00 release of Titan Attacks is this new trailer wot I have done…

Cas has also done a few fixes – so if you had any problems with Linux freezing, have a go and see if it’s got better.

Linux Ultrabundle Fixed

I’ve just uploaded a hacky fix to make the Ultrabundle games work properly on Linux. If anyone could let me know why Frame.isActive() always returns false on Linux I’d be grateful. Grr.

Revenge of the Titans Updated to v1.80.13

Humble Bundlers – download the update from your Humble Bundle page, not Puppygames!

Revenge of the Titans also got an update which actually changes a few things, some of which will make whiners whine, but as that’s what whiners do, we shall leave them to it. Amongst the changes is that the resolution of the game has now been fixed regardless of your screen’s aspect ratio. It was supposed to be like this before but because of a bit of a logic error it never really worked as intended. Now it does. You should find the game now resizes to any size you like when running in a window (press “P” to pause and ungrab the mouse).

Balance & gameplay changes in the game are as follows:

  • The overall difficulty level of the game has been slackened off a tiny bit. You will be able to hoard a little more money before things get really tough. But hoarding money is not the way to win this game anyway. Spend it on defenses! Or as we like to call them here in Blighty, defences.
  • Battledroids and repair drones have been nerfed, and are now produced in slightly fewer numbers.
  • The repairs that repair drones do now actually cost you money. The repair cost is 10% of the basic value of the building per hitpoint restored. The base, having no cost as such, costs $750 per hitpoint.
  • It’s now running under Java 7 on Windows, and should see about a 20% boost in performance, which you won’t notice really unless your machine is marginal in the CPU area.
  • Fixed a few typos here and there
  • Fixed a bug where you the difficulty was not being attenuated when you were being kicked in by the Titans. This has been in for ages! I did think it was a little odd that people were complaining quite so much about difficulty – turns out the little tweak that was in there to allow players to snatch victory from the jaws of defeat was broken!
  • Nerfed boss hitpoints a little
  • Any of you running on Steam will be delighted to know that we have added Steam achievements and Steam cloud support!

That little lot is bound to upset loads of people but, well, you know, they needed fixing. You’re unlikely to really notice unless you were heavily into repair drones, or you were finding the game too hard – in which case, give it another spin, you’ll probably get a lot further before you hit the Easier Level button.

Droid Assault – tweaked!

And it is a proper tweaking. Firstly and without further ado, go and download it and while you’re waiting read about what we’ve changed.

Why we’ve tweaked it

Before I tell you the exact nitty gritty of what’s changed you might want to know why we went monkeying with the secret sauce with one of the greatest videogames ever made, eh? Well, it all stems from the fact that Droid Assault is going to wind up on Steam in the not-too-distant future, and your average Steam punter is perhaps a little more discerning (or shall we say, “scathingly critical”), en masse, than you delightful and forgiving Puppygames fans are.

Droid Assault suffered a few arbitrary and unnecessary limitations in various areas. Firstly it was designed around a rather crappy 320×320 display area (along with our other two minigames, Titan Attacks and Ultratron). The window was fixed, square shaped, and decidedly a bit weird. In this modern day and age it seemed a little incongruous.

Also, the game did rather suffer from being somewhat mindless. It started off reasonably sensible but by the time you got to, say, two thirds of the way through the game, it became an almost random frenzy of blaster fire; 90% of the droids were blown up, including often most of your own droids, in the first 10 seconds of the level, leading to a couple of minutes of relative tedium. Again, this probably wasn’t going to satisfy the relatively eclectic tastes of the Steam demographic, many of whom clearly prefer deeper, more involved games, as our runaway success Revenge of the Titans has shown us.

So, I wanted to make the game a little deeper and more tactical than it used to be, and the following raft of changes is chiefly aimed at getting depth and tactics into this game to replace the random destruction.

Steam keys! Eurogamer review! Megatitan attack, Ann Arbor, Michigan!

First of all, the Steam key generator wotsit is now up and running here … and hopefully it works too. Go try it blog squadron, then we’ll fix it when we find out it doesn’t work, and then we’ll send out a newsletter.

Secondly, we got a very nice review on – 8/10 aint bad and it’s full of nice quotes too …

Hundreds of Titans will die, but still they come. As levels creep towards their end, the apparently endless spew of chomping 2D horrors finally peters out, the frown will lift from your face, the sweat will be wiped from your brow, and you will feel good.


Titans has been continually honed during approximately 38 million years in beta, and it shows.

…for example 🙂

And thirdy, worthy of it’s own post if it weren’t for the overdue Steam keys thing, we bring you breaking news…

I have photographic evidence of a Megatitan attack during a street parade in downtown Ann Arbor, Michigan yesterday. An entire album of evidence!

Pity these hapless souls who you see carried in the wake of its destructive power! I was an eyewitness, and I count myself fortunate that I lived to tell the tale! Crowds gathered on the sidewalk, amazed at its mighty roar– an echoing bellow of fury as loud as a megaphone!

The creature defeated Mario. It defeated Wallace and Grommit. It even defeated a camel and an octopus. Nothing could stand before its might!

Who, then, saved the planet earth? The alien invaders had failed to account for one thing. On this planet, H20 falls from the very sky itself. This element was the only thing that could penetrate a carapace of pure cardboardium!

I urge you to spread news of this invasion! More photographic and video evidence will be forthcoming!

your faithful correspondent,
Matt Arnold

We will indeed bring you any further updates as soon as we get them – who knows where the Titans will strike next!

News update!

Just as we we’re going to press, as they say, we’ve received further footage of the days events…

Bigger than the one we bagged in Trafalgar Square! Had that one stuffed, we did. Jolly good, eh what!



1920 x 1080 Revenge of the Titans wallpaper

Here’s the first wallpaper, which is a modified version of the image that will be gracing the Steam store soon, touch wood…

Click on the image for compressed .jpg version, or you can grab an uncompressed .jpg or .png (which Windows will convert to a .jpg anyway if you set it as the desktop background, I think.

Will be putting up other sizes, and getting special versions done for those that helped with the Mac icon, soon! … though that’s a special Puppygames soon 🙂

ペイントツールSAI ftw!

There’s another wallpaper image to come as well, along similar lines, at a later date. Here’s how it looked at an early stage in PaintTool SAI, which really is the dog’s ‘nads if you’ve got a tablet, and can’t draw for toffee*, like me…

Tune in tmrw to see the finished thing!… Steam permitting.

* It doesn’t really make you any better at drawing in general, as you can probably tell by my efforts, it just makes it easier to draw smooth lines with a tablet with it’s cunning adjustable stabilizer wotsit.

Mac users – help needed!

Cas has a Mac. It is broken. I’ve done a .icns with a 512px square image for the Mac dock thing or whateveritscalled – but no way to test. As far as I’m aware the 512px image in the .icns is only used in the dock thing and should look something like…

… so Mac users, your challenge is – can you get to preview a .icns file in your dock wotsit, is this the only place a 512px icon is used, and does it look any good, or does it look a bit poo? You can download the .icns here. Winner gets a brand spanking new yet-to-be-seen signed wallpaper with your name scribbled on it! Or something.

oh and ‘Arm of the Lord’… just the first image i grabbed from google 🙂

Endless Mode!

I’ve just uploaded Revenge of the Titans v1.6 here:


The following tweakery has been performed for your delectation and continued amusement:

Bugs Fixed

  • Again at certain resolutions the map scrolls past the edges
  • Gold medal awarded even though level made easier
  • Mysteriously reverting to earlier planet when resuming
  • info panel remains open when HUD hidden
  • Having your progress reset once you get past Earth

New Features and Enhancements

  • Add a “sell stuff” hint or two
  • Endless mode!
  • Movement animation of stop-start gidrahs looks better
  • Stop-start gidrahs move in a slightly different way


  • Crystal reduction as player gets richer slightly less severe
  • More crystals!
  • Blast cannon damage buffed to from 12 to 16


  • Much better frame rate limiting code
  • New animation commands to avoid XML duplication

As per usual, download and install over the top of your old version. Also as per usual, all your progress and saved games are invalid – bah! – that’s the perils of beta software. So I advise you start a new profile from scratch and test Endless Mode for me 🙂

Revenge v1.51 released – you asked for it!

We’ve been listening to your feedback on the Revenge of the Titans beta over the last few months, and with this new update (v1.51) we’ve attempted to address some of the most requested changes. And of course there’s a load of other tweaks, not least finally the ability to sell buildings! Here are the download links…

Mac OS

Don’t forget to check the version number to make sure you’ve really gotten 1.51 installed. Here’s what’s new, changed, fixed, twiddled, and nerfed:

Bugs Fixed

  • Fixed: stuttering sound (hopefully!)
  • Fixed: HUD money updates when intermission screen is showing
  • Fixed: Reloading a turret in build mode should stop build mode
  • Fixed: Can’t reload a turret or collect a factory when in Build mode
  • Fixed: creating path for gidrahs overwrites odd ruin tiles – needs to either leave them or delete all tiles associated with the ruin
  • Fixed: dialog text not centred on game over
  • Fixed: Apostrophe key ‘ now correctly selects autoloader for build
  • Fixed: Load/Save. Again. All files now stored in user home directory.
  • Fixed: Gidlets now only immune to explosions when spawning
  • Fixed: Ruins used to block blaster fire in their bottom left corner: this is now specified per ruin for the whole ruin or in a mapping attribute

New Features and Enhancements

  • Medals
  • Ranks
  • New intermission screen
  • New ESC menu
  • Wired up ESC button on HUD
  • Completely new in-game UI
  • New Game Over UI
  • Added the in-game menu to the research/story screens so you can quit out at that point.
  • Change the way shield generators work
  • Wire up new options (to hide various GUI stuff)
  • Rockets now explode when they hit the edge of the map
  • New research GUI with all the stats and two different views
  • Sell mode
  • DEL key wired to Sell mode and middle mouse button
  • You get 10 seconds to sell a building after construction in which you’ll get 100% of the money back (like an undo)
  • Laser to be able to fire into mountains (turret needs to be able to see too)
  • Appropriate story tweaks when flying gidrahs appear re: lasers
  • Removed [X] button from hints panel – click anywhere to close it now
  • Hints now remain onscreen for 7 seconds max
  • Top HUD fades out as mouse approaches
  • Bottom HUD now hideable with toggle button (INS key)

Balance Changes

  • Gidrahs now get a little more urgent and fearless when the timer runs out
  • Nerfed damage bonus for alien anatomy to just +1
  • Increased research cost of a few things
  • Nerfed laser/rocket ranges a little
  • Saturn gidrahs now a teeny bit harder
  • Slightly increased saucer duration on earlier levels, decreased on later levels
  • Reduce crystals available slightly now Sell button implemented
  • Tweak tuning: game needs to be tiny bit harder tiny bit sooner

Internal Stuff

  • Completely change the way game metastate is persisted
  • Store exact representation of level instead of relying on dubious random number seed
  • Gidrah now uses 1/32th the RAM courtesy of using packed bits in ints in its tiny brain
  • Awarded a non-repeatable medal sfx
  • Awarded a repeatable medal sfx
  • New rank sfx
  • Sold sfx
  • Can’t build sfx
  • Insufficient funds sfx

And onto a few pics…

We’ve had a fair few requests to be able to see the statistics of researched buildings, and to see in some form the research connections between technologies and buildings. Here’s the new Research screen showing those stats, and the improved table and the new tree layouts…

(You can read more about the changes in Research GUI for the Tweak)

Adding the requested ‘Sell’ button required a HUD redesign, so we made some oft suggested alterations as well…

( more info here: Revenge of the HUD Redesign and Revenge of the HUD part 2 )

The old in-game ESC key menu has been given a restyling, and is now accessible from a HUD button. You can access this menu from the various Story and Research screens by pressing ESC too. Options on the Game Over screen have also been updated…

And last but not least, the Achievements dialog showing Rank and Medals…

There’s also a new Level Complete dialog – though that looks a bit pants at the mo, so wont bother with a screenshot 🙂 That’ll probably get a bit of a tidy up in the final polish stage of development.

Next up on the todo list – Cas will be adding Endless and Survival game modes, and I’ll add badge graphics for ranks before making a start on the Titan levels. The jury’s out as to whether to tackle Endless or Survival first, but right now we’re hedging our bets with Endless mode, which is like the current campaign mode, but without a story, or… an end. Just level after level of slowly increasing size and difficulty, drawn randomly from the scenery we’ve done so far, until you are defeated (and there’s only one life). We expect Endless games to take hours to play, by which time you will probably be a gibbering nervous wreck.

Research GUI for the Tweak

Next up for GUI tweaking is the research screen, which currently looks like this…

There’s 2 major changes to make that people have requested:

  1. to be able to view more complete info and stats of already researched items
  2. some way to tell what research item leads to what, rather than effectively having to guess

The following images are first thoughts, and quick mockups – I know they don’t make a lot of sense as to what’s being hovered on,  refineries don’t lead on to robotics etc. 🙂 … Continue reading

Revenge of the HUD part 2

Thanks for all the feedback on the HUD changes – it seemed opinion was split between versions 1 and 2, but with the majority in favour of version 1, so I’ve gone ahead and sorted all the graphics and XML for that.

It may be possible to add some option to choose between the two at a later date, and I’ve arranged the various buildings so that they could potentially open up from category icons in little panels of 1×3 or 2×3 building icons… but as its taken 2 and a half days of fiddling to sort the HUD out so far I don’t think I’ll have time to do that before the next release which we have planned for Sunday.

This is how it was looking before…

… and here’s how it looks now….

Changes made…

Continue reading

Revenge of the HUD Redesign

We’re going to be making a few changes to the buildings/powerups panel. Here’s the current HUD….

First of all, and by popular demand, we’re going to add a sell button. Unfortunately there’s not enough room to squeeze it into that bottom panel, as that’s about as wide as it will go on a vertical display – the max width when vertical is shown by the dotted lines.

We could make the icons smaller to squeeze it in, but some people have also commented on the icons being too small to tell apart easily as it is, so that’s something else that would be good to address as well – magnification on hover being one suggestion.

There also needs to be a way to be able to hide the buildings/powerups panel, as it prevents building along that bottom edge.

So, 2 different designs after the jump…

Continue reading

Saturn released!

Well, we’ve finally released the Saturn levels for Revenge of the Titans under the guise of version 1.5! This has been quite a complex release, what with the addition of several completely new alien types and a whole new world, and an awful lot of fiddling with balance, bug fixing, enhancement, and so on. Without further ado, here’s the links:


Mac OS


Like last time it would probably be a good idea to play through from level 1 again with a new profile, as the amount of money available in the levels is somewhat different now, as is the cost of researching various things.

And here are some pics…

Yes, the boss is armed with a laser. No, he’s not very friendly.
