I came across this on RPS the other day and had a gander at the trailer (I do vaguely remember the name from an old article that they wrote about it).
It’s a small arena tactical game, where you have AI controlled bots that go out and battle another team of AI controlled bots - YOU do the programming for your units though.
The AI creation is done through the use of a flow-chart process, where you set up commands and string things together, making the ‘AI’ better or cock it up completely and your bots just mill around in a circle and die.
It’s in Alpha at the moment, but is listed on Steam as well. You can get the Alpha now and it will give you a Steam key as well upon full release.
