Pro Fun top-down shooter gameplay
Gun Bros uses the now-typical dual joystick control scheme with a top down view. The core gameplay is area-based and has you fighting against waves of enemies to clear the level as fast as you can.
Con Monetisation model forces a lot of grinding if you don't pay
Although it is possible to unlock all the weapons and beat the bosses without paying, Gun Bros forces you to do a lot of boring grinding of the same levels over and over if you don't buy some of the in-game currency.
