If you use grenade launcher in CoD4
"I say and I quote:-
"It's a legitimate strategy!!!"
No I kind of agree,it's not appropriate for high levels,starting off I guess it's the only way to rack up kills unless you have decent guns unlocked etc,but generally it's bad :(
Noobish weapon"
I disagree about it being noobish. I use it when tactics call for it. For example, say two enemies run into a doorway and you just happen to see them a split second before they get inside (e.g. the small, blue painted, two-story building on Crash). Not enough time to shoot them (and shooting through a wall with an M4 is not always successful). What I do is bring out the grenade launcher and put a nade in the doorway (i'll usually get one of them). Then the other one, being the geniuses they are, will run up to the window, where I put another grnade and get him, sometimes even the other guy who was camping the stairway. Using the launcher also allows me to train using the iron sights in case I ever feel like getting into competitive play. But then again, the launcher scenariois only when I'm not practicing with my combat sniping, which takes up the majority of my play time.
