Gun Bros is a mobile application by Glu made for the iPhone, iPod Touch, iPad, and Android Phone. You take the place of Percy or Francis Gun as you fight through waves of T.O.O.L.'s henchmen. As you go further, you earn more Xplodium. You can then refine your Xplodium and sell it for coins. With your coins you can buy more weapons, armor, power-ups and refineries. There are currently 5 planets released.
Level Format[]
Each planet has 10 revolutions, which get harder, but the rewards get bigger. In each revolution there are 50 waves. The total number of waves for each planet is 500.
Bokor[]
The fourth planet, Bokor, has ten Hordes. To advance to the next horde, players must kill a 100 (times horde number) zombies. As you complete more hordes, the game adds a hundred to the number of zombies you must kill. Strangely, when going from one wave to the next, your zombie kill count stays the same, so you only have to kill another hundred zombies to get to the next horde, so it is easier to just start from wave one. As you advance through hordes, enemy attack and health is increased and enemies become more numerous.
Leveling Up[]
Your level determines your max health. Leveling up is achieved by collecting experience through killing enemies, pick-ups, Bro-Op challenges, or by recieving gifts from your friends. Certain guns have certain level requirements noted by the "Requires Level:" section in the expanded desciption of the weapon. The maximum level possible is level 200.
