Like BioShock and BioShock 2, BioShock Infinite is a first-person shooter with role-playing elements. In contrast to the limited spaces of Rapture in previous BioShock games, the expanded environment of Columbia provides for more dynamic combat challenges in Infinite.As Booker, the player must fight their way through Columbia using weapons and a variety of tools in order to complete objectives. The player may carry only two weapons at a time, and can collect other weapons and ammunition either from defeated enemies or from random locations around the city. In addition to his health, Booker is also equipped with a shield. When damaged, the shield regenerates after a few seconds, while health can be replenished with medical kits or food. Should Booker die, the player revives in a safe area but loses a slight amount of money; Booker regains partial health and is granted additional ammunition, while local enemies are also partially healed. Players can still recover from death should they lose all their money.
