When Mass Effect 3 launches on March 6, you're going to have a helluva job saving the Earth ahead of you. So BioWare and EA have decided to give you a head start by offering up some pre-order bonuses. Because you know you already want it!
Starting today, pre-ordering the game will get you the M55 Argus Assault Rifle, boasting quick-burst fire with better accuracy so you don't waste precious ammo. Additionally, if you pre-order the PC version through Origin, you'll also get the AT-12 Raider Shotgun, with a wide spread perfect for close-up encounters. On the other hand, if you're going through GameStop or EB Games, you'll get the N7 Warfare Gear instead. That includes the N7 Valkyrie Assault Rifle and the N7 Defender Armor (which has extra storage for ammo and extra punch for your weapons!).
So make sure your Shepard has the upper hand against the Reapers (and whatever else the universe decides to throw at him/her) and collect your pre-order bonuses. Or, you could just suck it up and do it the hard way!
