Busy state crosshairs gives you the yellow dot even while your busy, such as reloading. Seems kinda pointless but it's helpful if your "busy" and want to target at the same time.
makes allies neon blue and enemies neon red, can see them without a doubt. thats what xenn tells me anywayz, im clean on cheats although some are tempting.
im goin cheatless for the time, like i said some are tempting but i resist. and the ones i use would be the less obvious cheats, such as no fog, colored men, no breathing, no recoil, and distance id. i found distance id to be very useful for talkin to teammates
pfft weaklings... if you must turn graphic details to low and lower your resolution, its time to
a) get a new computer
b) upgrade your computer
c) build a pimp ass computer for cheap with a radeon 9700 so you can turn fog off legit
