I actually played around with making a script for this for v1.46, but it wasn't great. what i did was camcreate a small explosion far enough away to do a very little bit of damage. then i slowed down the time, set the fog in really close and played some sounds that i took from call of duty (i think). after a few seconds, everything goes back to normal. it wasn't great, but if it's really wanted i could work on it more...
