OK, so without sounding totally retarded.... I'm having real trouble mastering this whole throwing back a Live Grenade.
I'm have the Grenade gesture enabled, so in theory I should swing my left arm and the grenade should be sent on it's merry way........ but no, this does not happen.
After pressing '-' to pick up the live grenade, no matter how much I swing my left hand, nothing happens..... well except I blow up, but that's not a good thing.
I know I must be doing something wrong, so any help would be great.
