ive found a glitch! when u use fast foward button mortars lvl 2 and above doest shoot any faster, so dont use fast foward button, or just dont buy mortars
if any1 has problems on any stranded map (the spaceship) theres a room with a shield in the bottom, go there and if u jump in the roof of that room u can shoot through it, also u can camp with a sniper or railgun next to the shield
i just bought the doomsday, and its a beast! its like the spear but with higher damage and ur reload takes like almost nothing (its better than the chaos)
