Radiangames has just released one of the best XBox Live Indie Games you can buy. Not only that, but it's a single dollar (80 MS Points). If you have an Xbox 360, you should grab a copy.

If you played the first release in the series, JoyJoy, then Inferno is like a campaign version of JoyJoy. If you didn't, here's a longer explanation: You move an abstract circle around a maze of other circles which are all different colours and are trying to kill you. You blast lasers back at them, upgrade your lasers using gold, then blast them even harder. Over 30 levels of increasing difficulty, you're looking for the exit and destroying anything that gets in your way.

Once you've completed the game by yourself, grab three friends and play through it again but with back-up. Four players can go ballistic through the campaign, and it offers the kind of fun which should only really be prescribed by a doctor. Did I mention it's a single dollar?

If there was any justice in the XBLIG world, this would be the next I MAED A GAM3 W1TH Z0MB1ES!!!1. Go forth and purchase.

[Update: The contest is now over - thanks to everyone who gave us their story! You're all utterly mental. Congratulations to our winner THE_Grosser, whose story of tent-rolling and toilet-going gave us a right old laugh.]

Shank was released via the Xbox Live Arcade last week, and is as fun as I hoped it was going to be. Just watch the above video for a glimpse of the ridiculously splendid moves you can pull off as our beefy, one-track minded hero (although ignore the EA symbol at the start - it started off as an indie game, and the indie spirit is still there!).

The game follows the story of Shank, who is on a mission of brutal revenge. We've got a copy of the game to give away to one lucky IndieGames reader, and winning it is simple: give us your best story of personal revenge. Maybe a friend betrayed your trust and you gave them a taste of their own medicine, or perhaps you were made to look stupid and getting your own back was the only feasible option... whatever the case, post your best story in the comments below, and we'll pick the best one at 6pm GMT tomorrow (September 3rd).

Don't forget to enter your email address so that we know where to send the code to if you win! (Email addresses aren't publicized). Good luck!

I don't think I've seen such a fitting name for a game in a while. Chaos Invaders is an utterly mental take on the classic shooter, in which dead enemies can be used as weapons.

Shoot an invader down and catch them on your ship, then launch them back at the remaining baddies. The boss battles look like stupidly good fun - you can chip pieces off a huge mothership, collect them all in a big pile then fire them back and cause havoc. The game will land on the webs for free any day now, so we'll make sure to keep you posted.

Over the past decade, blend trees have established themselves in the games industry as a reliable and flexible technique for animating game characters. However, it can take a lot of development time to build up an efficient runtime and powerful toolset, and obviously middleware companies are stepping up!

In this interview-style presentation with Jason Turbin, you'll find out everything you need to know about Havok Behavior, the middleware animation system that powers WORLD OF ZOO (among many other titles). Jason goes behind the scenes into the architecture and implementation of Havok Behavior, and provides insights into the tools and how they are used.

The world of indie development has swallowed yet another AAA game designer! Mr. Shane Neville left his game development career of 14 years to start his own indie gaming setup, and his first game is coming soon in the form of Ray Ardent: Science Ninja.

Across 15 levels, Ray runs and jumps lots, using his ninja skills to traverse pits and baddies galore. You'll also be able to collect special power-ups which can be combined to make Ray that bit more powerful. At first the voice-over wasn't my cup of tea, but once he started shouting things about science, I thought yeah OK, that could work.

It's released in September anywho, and you can read all about it, extra extra, over here.

Originally created in 48 hours for a Ludum Dare competition, 5 Colors Pandora has now been beefed up a little and given music, which adds a whole new element to the game. You're tasked with exploring the monochrome world, finding a way to fill it with colour.

It's a bit of a slow-starter, but eventually gets really tricky with some clever puzzles. Touching big buttons around each section of the world switches you between levels, and pressing X allows your stickman to turn into a box and float. If you don't have time to play through it, feel free to watch ortoslon's playthrough above.

Otherwise, go give it a download.

Broken Rules' And Yet It Moves has been released on WiiWare, along with the above launch trailer. And it's a rather awesome trailer at that.

For those not in 'the loop', And Yet It Moves is a platformer in which you can rotate the world to turn walls into floor and vice-versa. The WiiWare edition is slightly different to the PC release, in that you can specify how much the world is rotated rather than turning it a set amount. Watch the video from a couple of weeks ago but a better idea.

The game is available to download from the WiiWare service for 1,000 Nintendo Points ($10).
