if its in the game its not cheating. Adapt.
doubt its viable on many levels, unless you really want to learn how to play it. so far I can only use it on b2 and archives. which i got another 55 with.
It seems to vary level to, though probly because strafe lines are hard to follow, I couldnt get depot 26, though i never did have a decent train shot, and my strafe liens were always innacurate. But for levels like train, bunker 2, archives, facility, or anything else really tight, im sure it will be useful
If we found out ammo on screen caused .3 time saver, I know you wouldnt bitch about it, and would use right away cause its more conventional, but cinema, its basically like learning a new control style.
