Great Review of a great game. It is very close to counter strike in the way of weapons, also like counter strike, if you get shot in the head with any type of bullet you are dead, no questions asked.
If playing this on live though, A few unwritten rules apply. First off, most people objext to the .50 cal sniper rifle. It's waaay to easy to use, and most concider it cheap to use it. (Like using the AWP in CS), and most servers disable grenade launchers since by most, it is concidered a cheap weapon. The best thing to do is ask what weapons are not allowed in a game (adversarial play that is), so you know what is acceptable. This game is not like other games you might have played. If you rush into a room with 2-3 bad guys (coop or adversarial), You can count on dying. This game like the reviewer commented, uses more stealth than rambo. So if you rambo through a map, you will probly get that death/kill ratio pretty messed up. Not many kids play this game online that I have seen. Mostly older people with alot more patience, so it's not just a run around like a madman kinda game. You will find yourself slowly peeking around corners with your thermals on taking the silent aproach on the coop missions (especially when you watch your 3 other team mates die by a few hits after rushing).
All in all, this is a great game. Until CS comes out, this will be the realism king (or you never know, it *might* survive cs's fandom, but I won't bet on it...)
BTW Guyver-X: How you like them trippy tear gas grenades, better than drugs :evil:
Along with the Flashbang, wow, nice effects than just the standard white screen you get in CS.
