Getting your hands on as many weapons as you can is the name of the game in Alpha Protocol. And the only way to get your hands on the Stealth Weapons Pack is to pre-order the game from Best Buy. The Stealth Weapons Pack includes the Hamilton Marksman High-Accuracy Pistol, the Samael Typhoon High Recoil Control SMG and a bonus arsenal of ammo and mines, to give gamers the edge in the battles ahead. Sega and Obsidian's Alpha Protocol will be available June 1 for the Xbox 360, PS3, and Wii.
