It's pretty good. They definitely got the feel down right. I don't know if you played
Resident Evil 5, but it has a similar control scheme, except that you can actually shoot while moving and there is no quick turnaround in
Dead Space. The way you kill monsters (necromorphs... creatures built from dead flesh
) is by dismembering them; direct shots to the head/torso generally do nothing.
But ****, going through a spaceship, the claustrophobic tunnels... The necromorphs use the vents to move around, so you'll hear them skittering by. All the inventory control and maps and game logs are realtime, done up in a holographic display from the main character's gear. Your health is on your suit, so there's literally no HUD. The immersion is very very good. Luckily there are lots of save points, because I tend to get killed somewhat often.
