I just got it today and started playing it alone in a dark room. Then I started walking around and didnt have my heat sensor googly things on and walked in the wrong blace and got BLoWN TO FUCKING PEICES and it was loud as shit too. I got scared, so I'm not playing it for a while. I think my heart just settled down.
i got it. i only played single player for a bit. it seems to have a little bit more realistic physics. kindof like MOHAA to Spearhead, it just feels different but its great.
Multiplayer kicks ass.
Mercenaries: first person view, you have to lay traps and stuff, it can be hard but its still fun.
Shadownet: awesome but you actually have to be really stealth, you cant afford to get in a gunfight. it is so cool to shock someone then sneak up and snap their neck. thats the only lethal way to kill someone.
