OK first off this weapon is the biggest piece of **** ive ever seen. I have hit enemies with the grenade numerous times and they walk away unscathed, ive landed grenades in foxholes with people and they walked away fine. the damage this thing produces is pointless as if the enemy aready hasnt been hurt the nades dont do anything. secondly ive read up about bouncing grenades around corners, setting up tacitcal minefields, and airbursting? it dosnt do any of that, its basically running around with a damn potatoe launcher shooting water balooons....

yeah I'm pretty dissapointed with the L-Tag as well, it's one of those guns that was awesome in the story mode, but not so much in multiplayer. Anyone try out the MIKE in mp yet??

I can't kill anyone with it either, but i saw a clip from one guy who seemed to have gotten a really good grasp on how to use it (on this forum). But even if i can't kill anyone, it's still madly fun to use.

That's the video from the guy 2 posts beneath you, seems to know how to use it pretty damn well.
Should ask him for some tips, heh.
I svck with it as well though.
