The Bomb is a Pickup that activates automatically once auto-selected (except when using SADIST cheat). Upon activation, the car turns black and its antenna starts burning down like a fuse. After ten seconds, when the fuse reaches the bottom, the car blows up.
While a bomb can't be defused, the player can pass it off to other racers by touching them. The victim gains the remaining fuse time.
In Re-Volt 1.2 or RVGL, hitting a Clone Pick Up while the fuse is still running will result in the car exploding immediately, discarding the remaining time. It is not the same in the legacy versions, where the fuse keeps on running even when hitting a Clone Pick-Up.
If you carry an active Bomb and pass it on to another player, you will gain a short period of invulnerability. While it is active, they cannot return the same Bomb to you, but they can pass you others.
