I am playing through on Supersoldier level as I like a challenge. I figured it would be about the same as Delta in Crysis but to me it seems much harder. It does make it a bit more challenging. Some observations...
1) The AI act to much like computers and don't react in the way a human soldier would. I know making AI act totally human like is too much to ask but it seems the nanosecond I come out of cloak every enemy CELL instantly fires exactly on my position. Would it be possible to program more human like reactions into the enemies - each AI has a scanning range and a viewpoint, some randomness to how they visually identify you and if they're on the other side of the map then it should still be fairly tricky to actually see you.
2) At times it seems the AI can see me even when in cloak.
3) Enemy AI can see fallen comrades even behind walls.
4) Enemy AI can see you behind walls.
I don't expect any of these issues to be addressed in this game but for future reference.
