Okay, got another release for you. This is the AITestBase project with the Behaviour Tree.

Win32 only right now, I'll drop the source off tomorrow when its cleaned. Giving in for the night now, been working on this for around 9 hours today and I've had enough. Progress may slow down for a few days as I'm expecting a new GFX card tomorrow or Wednesday so I'll have to take a few hours off whilst I install it and give it a spin. Anyway, The behaviour tree is loosely based on LibBehavior. Give it a go, I've found that usually the player wins right now, but I'll put a bit more effort into making it closer tomorrow.
