Just bought this today.
The demo isn't representative of the game at all.
Those guys talking about "game of a previous gen" are right.
But it's not a bad thing.
The graphics are excellent, at least the lighting is.
Some low-quality textures here and there but it's not a big deal.
The alien A.I rocks.
The "previous gen" vibe is mostly in the SP.
It feels like you're playing half-life 1.
Also the animations (holding gun loops, opening a metallic door, ...) are not AAA quality.
It's such a big license, it's frustrating to see B quality animations in it.
There's no mocap and every single anim feels "blocky" and jittery. Very rough.
From the camera movement to the hand anims to the predator idle loop.
This detail would have made the game much more better.
Exact same thing for the sound.
If you'd ask me, it seems they've worked on the marine first. The predator and alien play better and feel more lifelike.
The MP though, that's a different thing
Loads of fun to be had and a lot of players actually playing it.
I wouldn't have minded paying the same price for the MP only, a la l4d.
