It's a multiplayer game where you (a robot with a sword) run around collecting points (by killing other robots,) then cash them in by destroying yourself in a spectacular fashion. Robot homicide/suicide explained in comic format. The beta is open, so consider trying it out! (windows-only)
You also need Microsoft .NET Framework 3.5, but it will also install that for you via a popup if you don't have it, and try installing Plain Sight.
So you start with one point. Then you kill your enemies repeatily. Then yo get bigger and bigger as you kill. Then you blow yourself up in a spectacular way. Then you get points as you lose your upgrades and start over.
