Lol if you get missile creator level 3 upgrade, you produce more nuclear strike missiles than the ship (in normal mode) shoots. If you increase the firerate of course they slowly start depleting again. Maybe that stops at level 5 too.
Glitch: Finish a mission, when the mission complete sign appears kill urself. Back in the menu the sign u are dead is still there. Select yes and a miracle appears: (maybe it's different for u) a Jackhammer with triple flamethrower and 9999 bullets
Hey u can turn round if u have high sensitivity and low speed
+ this so everyone knows
(btw it can happen that u glitch out of the tunnel (i hoped to get an awesome score) but in red letters it says after a few seconds NO ESCAPING)
Tip to level and agin MUCH money:
Take first the paladin and level until 4
the you'll have the holy quake
you can use it then in the training grounds and the level gets finshed fast, so you can win much exp and money
Turning around is fun :D still working out the glitches and stuff, sorry about that :(
