A C4 is a placable explosive available in the traitor shop to purchase with credits. The C4 is a timed explosive and can be attached to a surface (Right Mouse) or dropped (Left Mouse) and armed. When armed, the timer can be set to go off anywhere from 45 seconds to 10 minutes. Armed C4s beep regularly, which can notify nearby terrorists, however, the longer the duration of the timer, the quieter and less frequent the C4's beeping will be. C4 can be disarmed by an innocent cutting a/the correct wire or instantly with a Defuser. The longer the duration of the timer, the less correct wires there will be, with a maximum of 5 and a minimum of 1. The terrorist who planted the C4 can instantly and safely disarm it by clicking the disarm button.
The C4 should be planted where there is a large group of people nearby, but where it is not easily noticeable so that an innocent won't stumble upon it or hear it and attempt to disarm it or call a detective. When a C4 is disarmed an innocent or detective can pick it up or destroy it. The detective as well can use the DNA Scanner on the C4 to find the DNA of the person who planted it.
- The C4 is a default traitor weapon but the Jihad Bomb is not.
