WHY CANT YOU DODGE A HUGE BULLET THAT CAN ONLY BE SHOT 3 SECONDS AT A TIME AND MOVES SLOWER THAN ANY OTHER BULLET IN SOLDAT. EVER.
Actually the speed increases as the player moves faster, which is even more deadly when they rush up to you. Keeping distance and hight between you and the M79'er by 'kiting' them and generally being cautious can help alot, but it's not always a viable counter in a fast-paced game like Soldat.
Though that 'dynamic speed' thing may be getting reblanced in the new version.
