On Tuesday February 09 2010 Mass Effect 2 fans will be able to get the new Cerberus Assault Armor and M-22a Eviscerator Shotgun DLC fof free through the Cerberus network. It should be available for all fans, both on PC and Xbox 360 at 12:00pm Mountain Standard Time.
Cerberus Assault Armor
Cerberus assault armor is designed for shock troops, turn the tide of battle against creatures or forces that would decimate normal soldiers.
-Increases heavy weapon ammo capacity by +10%
-Increases shields by +10%
-Increases health by +10%
M-22a Eviscerator Shotgun
The M-22a Eviscerator Shotgun is a longer-range shotgun with armor-piercing loads. This design also violates several intergalactic weapons treaties, so the M-22a is not distributed to militaries.
