- "Explosives fitted with a time delayed detonator."
Primarily used as a direct weapon, it can also be used to trigger accidents. It has a 15 second delay between throwing it and it detonating. Alternatively, it can be used as a melee weapon by bashing it into the face of a target.
- Fight Night: In the room adjacent to the gun storage room on the second level of the arena, a keycard is required to enter that area.
- It takes up the melee weapon slot, rather than the explosives slot; essentially, a C4 Brick and a Remote Explosive can be carried simultaneously.
- It is the only time delayed explosive in the game, though unable to be remotely detonated like RU-AP mine, but it can still cause heavy damage if timed well.
