Tips:
the first thing you will want to get is the center gun, then buy the first front shield, shield recharge, then missiles. the drones are a last thing to get really... rate of fire, needs to be maxed out then you can literally just spin slowly in a spiral and beat the game. hit + if this was helpful
long loading times, over powered AOE weapons and the idiots who glitch out of maps, make this a one star game for me unfortunately, sorry to the creator but the noobs using only rocket launchers and grenade launchers are ruining the fun. :(
