Last use at tick 304 (305th, counter starts from 0), made for demonstration purposes and later uses to write down technical stuffs (probably beats all WRs even SR50+TLx/TRx ones and improvable).
Great work! But why don't you kill a shotgunner and take his weapon? I think it's necessary for TASing all the episode. Or you just showed the fastest walkthrough of E1M1?
