Sam Gideon can arm himself a laser cannon if you pre-order Vanquish in Japan. Reserve the game to get a code for the Vanquish Limited Weapons Pack, which includes these three guns.
The Vanquish Limited Weapons Pack will also be available as downloadable content after Vanquish launches. A release date and price were not announced at this time.
Sega, as of this moment, has not announced a similar promotion for the North American launch. We don’t have a firm release date for Vanquish in the West either, so there may be a similar promotion overseas. Vanquish comes out on October 21 in Japan.
Update: Sega Europe confirmed the same pre-order bonus. Vanquish comes out to PAL territories a day later on October 22.
