With Enemy Territory relying a lot on AI in single player, what kind of developments have you been making in this field?

Hollenshead: We've taken a lot of the original Wolf AI - which we thought did an excellent job of emulating what human behaviour would be like in those circumstances. There are certain things you can get away with in Zombie behaviour, they just come at you mindlessly. But soldiers present a different challenge and we're in the process of adding several elements to that side of things at the moment. But single player is really still just at a pre-alpha stage right now as we've been focussing mainly on the multiplayer game till now. The biggest challenge for us is having a team that you command that are independent enough to act realistically but not be too advanced that they just go off without you and complete the objectives.
