Well, it depends on what kind of AI for enemies you need.
If you need pathfinding, you'd be better off contacting Sven - he might be able to help. I don’t work with pathfinding algorithms since they put a heavy load on the game and only work well with a very small number of enemies (2-3 per location).
Otherwise, i could just write a simple AI, similar to the built-in one in the engine. It could patrol and react when it sees the player, but its movement would be limited since it wouldn’t actually navigate the environment.
