Nuclear Fission Explosive
The Nuclear Fission Explosive device is used in conjunction with the Nuclear Authentication Disk to destroy the station. Detonating the nuke will end the round.
The Nuclear fission explosive is located in the Vault. The Nuclear Operative's nuke is contained on their shuttle.
Arming
To arm the nuke, You need the Nuclear Authentication Disk which is found in the Captains locker and the Nuke Codes found in the nukie shuttle or faxed by Central Command to appropriate fax machines.
Once the disk is inserted into the device you will be able to anchor the device to and from the floor. You will also be allowed to enter the nuke codes.
Once the correct code is entered you will be able to arm the device. Once armed, the station will go into Alert level Delta, the device will announce its location and start a 300 second (5 minutes) countdown. When the countdown reaches zero the device will explode the station and end the round.
Disarming
During the countdown the nuke can be disarmed via fiddling with the wires of the device.
