Build the ultimate battlefield with Transformers War for Cybertron Siege figures. Siege plunges fans into the epic fight to survive on the final day of the Autobot and Decepticon battle to control Cybertron. The Decepticon resistance army and the Autobot counter-resistance fighters gear up with the universe’s most advanced modular weaponry, including weapon mode Battle Masters — sentient bots that convert into weapons. The WFC-S1 Firedrive figure converts from robot mode to Duo-Charge Electrostatic Photon Cannon mode in 5 easy steps. Use the weapon mode to equip other Siege figures with larger mission loadouts and use the included Fire Blasts to simulate blasterfire or explosions firing from the ends of weapon mode Battle Masters or other Siege weapon accessories (not included).
