Time Bonuses are a tall statue-like object. When hit (or interacted with in RE4), it gives th player extra time on the "The Mercenaries" minigame, on the Resident Evil 4, Resident Evil 5 and Resident Evil 6 editions, as well as the spin off game, Resident Evil: The Mercenaries 3D. Time given by time bonuses can differ between 30 seconds to 120 seconds in RE4 and RE5. Extra time can also be acquired by performing melee attacks that kills an enemy, adding an extra 5 seconds to the time remaining.
In RE6, maps with a bigger amount of time bonuses have some of them set to only give the player +30 seconds to the clock, with +90 being the maximum in smaller maps, there is a skill that can be obtained which upgrades the time obtained from time bonuses in the Mercenaries.
