I know u guys keep saying fullscreen works on other websites, but that isn't true, because i've checked. Get you shit straight and fix fullscreen, or at least make the mouse static so that you can actually turn around 360 degrees without the mouse sliding outside the screen.
use the barret .50 caliber then shoot out all your ammo on all your weapons then aim (left click) then while aiming shoot (you dont have any ammo so you won't be able to shoot, instead the aim will zoom out and you will almoust aim at your own character) [PLEASE FIX THAT GILTCH] although it's awsome :)
Thanks for the heads up solider, we are re-investigating this issues. Rest assured, this fix will be included in this weekends updates.
