Take a look at the pre-order items you could get by pre-ordering Mass Effect 3 from GameStop, Best Buy, Amazon, Wal-Mart, or on Origin.
Prepare for the Reaper invasion today and secure your pre-order gear! When the enemy has overwhelming numbers, bring the M55 Argus Assault Rifle into battle and unleash rapid-fire bursts to even the odds.
Shrug off enemy fire with the N7 Defender Armor and its amplified shields, then drop the opposition with high caliber fire from the N7 Valkyrie Assault Rifle. If the enemy gets too close, stop them dead with the AT12 Raider Shotgun and its superior firepower.
In addition to the the weapon bonuses, Amazon is also offering $10 Bonus Credit.
