The Nuke can be found in three multiplayer levels: Tears Of Horatio, Withering Heights, and Dino-Depot. Note: Do not have the "Unlimited Ammo" option in the multi-player options menu activated or the Nuke will not appear. You can still use the "Unlimited Ammo" cheat in the cheat menu and get the Nuke. The "Unlimited Ammo" cheat does not give you unlimited Nukes. The Nuke will respawn after a period of time.
