oorah man...it is the greatest game ever..most realistic tactics ever (ill get to it later) and it is hard core marine man...down to the things they blurt out at random times.
tactics: awsome...truly awsome.if your going down a street, they use the double colum tecneich (i cant spell on computers) and you have a full fireteam: automatic rifleman, teamleader (you) rifleman, and assistant gunner. they use the "ready, team, fire, assist thing, they use proper tactics for taking down a room, you can make opfors surrender, there are high value targets that you go after, you call in cobra support and sniper support and mortor support (mortors sound crappy) and you have to call in coremen. they surrpress the right places and right, you have an m16 with m203 and your ar has an m249, the other guys have m16s......i could truly go on and on.
gameplay: really realy fun...it doesnt get old or repetitive, awsome and fun online play (though no one is on anymore) and is just really fun
enviorment: desert urban but simply outstanding in every way, authentic bomed out buildings, blown up cars, civvilians trieng to make a living, opfors hiding in random place (if one is some place then you die, he will be some where else when you restart)
weapon authenticity: exaclty like real ife, he reloads right and everything
gear: exacly what they wear in real life
people: you friggen get to choose what you look like!!!!
thats all i can think of but tell me if any of those tactics or somthing you didnt understand
