Refer to
http://www.staredit.net/?file=611 for information about Nexus 6.32 beta Heavy. That beta is perfectly playable, and "Heavy" means 4 civs at start and heroes every 15k.
This is a very incomplete project of mine to create a basic AI to fight against in Nexus Destroyers, usually 1h v 1c. I would possibly have allowed a team system, though I hadn't worked that out yet.
So far, the computer makes a combo of annoying units whenever you haven't selected anything, or it doesn't recognize the ones you've selected. It will try to counter you partially if you select units against the left wall (the rest I have not implemented yet). It will also use heroes, currently in a predictable order, fully healing the nexus once or twice in its list of things to do. It will eventually try to do hero combos.
It's kinda interesting, but not very intelligent. Please try to fight nicely, and destroy its units instead of ignoring them. It's actually a bit difficult if you do that. It will occasionally self-destruct when it thinks you may be a threat at its base, while it's attacking yours with only a few units.
I think that's about it. project is on hold until further notice. feel free to use it and work on it if you wish. It's kinda fun.
