My personal favourite is probably the Famas with either a red dot sight or a silencer. I love how it just drops people with one burst. What's your favourite gun in MW2?
My favorite gun in Call of Duty: MW2 has to be the ACR. This gun was probably the most accurate in my opinion. I was able to spray and pray people across the map and not worry about the bullets missing. The ACR with the Scavenger perk I was pretty much unstoppable in Team Deathmatch.
since I see that the thread has been grave-digged from a long time back, I guess its safe to post now since mroe than one person grave-digged :/ anyway, my favorite weapon is the m21ebr silenced + thermal, with cold-blodded pro, bling pro, and ninja pro, with throwning knife and stun grenades I am literally invisible with that class, set-up
