Query: excellent graphics engine, AI a little predictable

OK, like everyone says, the graphics engine is the best out there -- the lighting from the flashlight and all the ambient lighting from the swinging lamps, flashing red alert sirens, etc, are unbelievable.My only problem was that the gameplay of the monsters coming at you turned a bit predictable after a while. Comparing this to Halo, for example, I enjoyed halo more in the sense that each monster acted drastically different, and there are "puzzles" in halo like having to figure out that those certain larva creatures will explode on your shields.I found one specific part of the game to be excellent -- because the monsters are coming at you so much for a while, there is a roughly 10 minute portion in the middle where things calm down, BUT you are still on edge waiting for something to happen! Good scripting with that.So, the game is great, but don't expect it to be everything you want and you will enjoy it more I suspect.
