Bugs Bunny & Taz: Time Busters

The main objective of the game is to collect all of the Regulator Gears scattered around the levels, which are required to progress through all four different eras: the Aztec Era , the Viking Era , the Arabian Era , and the Transylvanian Era . The gameplay plays much the same as Bugs Bunny: Lost in Time , retaining Bugs' traits (sans being able to pick up and carry crates, or push heavy objects), but introducing new ones to Taz, as well as a co-op mode where one player can control Bugs, with the other controlling Taz; alternatively, the game can be played in single-player , with the player having to switch between controlling Bugs and Taz throughout the game. Both characters need to be used to make use of their unique abilities to make areas accessible and defeat certain enemies. Unlike in the last game, both characters are able to swim (albeit Bugs is faster), and Bugs is able to climb ledges for the first time in the series.

Jumping on Taz's head allows Bugs to climb higher than in the last game, and if Bugs remains stationary around Taz for too long, then he will bite him depleting his health . Health can be distributed between characters if one attacks the other, and carrots are the source of health for both. All eras are accessed from the central hub level Granwich. Once an era has been completed of its levels, a boss must be confronted and defeated, along with collecting nearly all of the current era's gears, in order to unlock the next era.

After the last era is completed, the player is given two different endings based on if all gears were collected. If all gears are not collected, the player can choose to continue playing to collect the remaining gears.
