I'm sorry but by today's standards this game is pretty weak. I can appreciate that it was good back in the day, but it's hard to play now. The controls are very clunky, aiming is horrid (you get a tiny dot), so you get hit a lot, so you die a lot, and they don't give you many health packs. Health packs are dumb. Ever since Halo, I can't stand playing without them now.
If you want a current 'slow motion' game, play F.E.A.R. or Time Shift. The graphics are definitely dated and a couple controls are just backwards. For me to rent a game and play it all the way through it has to grab me and I just don't get that.
The one really good thing about this game is the story. It's told VERY WELL, makes you want to like it, but I think I caught this game too late. I'm told it's good on PC? Must be the mouse/controller issue.
