Until February 23rd, 2011, Mass Effect 2 players on Playstation 3 can download the Terminus Armor and M-490 Blackstorm Projector Weapon free of charge from the PSN Store.  After Feb 23rd, the Terminus Gear will be available as paid DLC.

Terminus Armor:

Like all modern combat hard-suits, the Terminus Assault Armor is environmentally sealed with an independent air supply for use in space and extreme planetary conditions, with an onboard "micro-frame" computer capable of running a suite of battle management software. To prevent detection by passive thermal sensors, body heat is channeled to the base of the feet, where it can be dispersed into the ground.

• Increase storm speed by 10%
• +1 magazine of reserve ammo for weapons 
• +15% shields

Blackstorm Projector Weapon:

The Blackstorm encases a few particles of matter within a high-powered mass-increasing field, elevating them to near-infinite mass and creating a powerful localized gravity well that draws nearby enemies and objects into itself. The rapidly-increasing gravity near the event horizon of the singularity rips the objects apart and then explosively hurls them away.

Two years after Commander Shepard repelled invading Reapers bent on the destruction of organic life, a mysterious new enemy has emerged. On the fringes of known space, something is silently abducting entire human colonies. Now Shepard must work with Cerberus, a ruthless organization devoted to human survival at any cost, to stop the most terrifying threat mankind has ever faced. To even attempt this perilous mission, Shepard must assemble the galaxy’s most elite team and command the most powerful ship ever built. Even then, they say it would be suicide. Commander Shepard intends to prove them wrong.
