1. Stuck & Stuck

Enemy AI walk to object, wall & friend friquently. This problem is breaking AI. Very annoying. I've hardly seen such a critical problem in Farcry/Crysis/Warhead, even all FPS/TPS which I played. Much much higher frequency than those. What are you doing, Crytek?

2. They don't notice object sound

Even if I throw object near Enemy AI, they don't notice. They don't have eyes & ears? Farcry AI can notice direction/sound of stone(player can throw it). Crysis AI can notice object sound easily. What are you doing, Crytek?

3. No reaction to useable object?

This isn't big problem. But I want to write about this. We can use phone, printer & etc... but, there is no meaning. There is no effect to gameplay. Enemy AI don't notice phone sound & etc. Add ears to AI if you have labor to such useless factor.

Good quality except these. Better than Farcry/Crysis. If Crysis2 doesn't have these problem, I can say the AI is the best in FPS history. But these some problems are making s***********************t. These problems affect gameplay very much. Please fix, hurry! Crytek should fix this as very high priority thing.
