Nice Try
Presentation is excellent, and it's a wonderful concept.
It's barely playable though, the later levels are extremely boring as it just comes down paying the entrance fee and hoping like hell that your bots wont act like complete morons (ie, healer charges into to pack headfirst, tank runs straight into a corner and is stuck there the whole match, and the bot with the best gun just spins in circles trying to shoot bots THROUGH the healer). 90% of the time this is the outcome, and given that some of the levels allow the computers bots to have access to better equipment.
I've never played the first one, but if this is IMPROVED ai... I'm glad I didn't.
I would recommend having settings for the bots, or a 4th component like a "AI disk" or some such thing, where you can give them a basic command like "Agressive" or "Support" because quite frankly at the moment you may as well flip a coin and call "heads" or "die".
