mmm i think it would be cool if u could press E to pause it, and then to unpause it press again 1 or 2 to select the mode. that way its near the hand.
so if u have to open a dor or domething just select 1 or 2 again, either way u dont have to shoot as u open a door...
so u can fastly press e and then change weapon to pistol or nade fast
Or the letter F thats not used
the best thing would be if u could select what key to press to pause it.
and to some friends this crush their ava when they press insert to wisp.
