I was really disappointed.
- The tutorial "restarted" for no particular reason two times
- The voice acting is extremely poor
- The rest of the sounds are extremely poor. Everything sounds flat and echoed. There's no footstep sounds, no sounds for climbing or descending a ladder, the Breed make very little noise and the weapons are extremely quiet. Not to mention explosions
- The graphics are all right is some areas but aren't up to par with most games. The textures looked dull and muddy and the game lacked some of the more standard effects, for example bullet holes or blood.
- The spawning enemies issue has already been brought up. Enemies magically appearing in turrets and snipers spawning out of thin air kills your enjoyment.
- The AI is some of the worst I've seen in a while. The last game to sport such amazing AI was 007: Nightfire. The AI includes features such as "run towards you shooting" and "ignore the fact that the person standing next to you got sniped". I honestly haven't seen such uninpsiring AI in a long time.
Overall I'd say that the game has two main problems. It lacks any degree of ambience and it has extremely boring combat thanks to the AI.
... Coming from a person who was really looking foward to it.
