Good game but needs better money system cuz 1 coin every kill and guns that cost 3000coins+ aint working out, and this game aint good enough to have real money spent on it.
This game is pure bullshit you only get 1 upgrade point every time u level and theres like 15 power ups to get each with at least 5+ upgrades, then you fuking overkill with the enemies...
u fight like 3 ZPCI each hitting like 100+ and each one of them has like 500+ hp while ur hitting 50's its pure crap this game needs some serious adjustments 3/5
