Let me show you how I managed to let the build a group of units (3 quads + 2 tanks) and send them off to attack the human player. This only works in Campaign mode and this is the only kind of units the AI will build now (although the AI can build any kind of unit).
For the upcoming 0.6.0 the AI is rewritten. This video showcases new AI mechanisms working where the AI is building 3 quads + 2 tanks , and uses that to attack. Using some debug mechanisms I can see what the AI sees (and the sidebar interactions). The game is still bugged, but it shows one of the features the new AI has. Using the idea of “build a force and do something with it” the AI can be expanded. In 0.5.0 the AI didn’t really got a lot of attention. It was randomly building things and sending units to attack.
