But that's not all, the developers have also revealed the pre-order incentives of the game. According to the press release:

In North America, pre-order bonuses* include special-ops armor and weaponry that are designed to boost Commander ShepardÂ’s skills and abilities. At GameStop, Terminus Gear is available with pre-orders, which includes the powerful Terminus Assault Armor and the M-490 Blackstorm Heavy Weapon:

• The Terminus Armor is designed for use in extreme planetary conditions, increasing run speed and personal shields, and augmenting weapons with an additional magazine of reserve ammo.
• The M-490 Blackstorm Heavy Weapon generates a high-powered localized gravity well, accelerating particles to near-infinite mass, and ultimately expanding the selection of heavy weapons available to players when they gear up for combat missions in Mass Effect 2.

Players that pre-order Mass Effect 2 at other retail outlets in North America will receive the potent Inferno Armor, which is used by officers to monitor battlefield conditions by recognizing elevated heart rates, and regulates sub-systems with extreme efficiency to allow for greater response times – together these abilities translate in-game into a negotiation bonus for Commander Shepard and an increase in run speed and augmented damage from combat powers
