Main improvements in this run are, once again, instant reload glitch. Using instant reload on the 5th gun (crazy dragon, 250dmg) gives an easy 1250-1500 splash DPS. If you ration out the ammo boxes, you can fire this weapon at max speed for the whole level. I actually got a 3:45 as a warm-up run without recording, due to better ammo box luck on Base 1. This run can be improved by at least 20sec.
