The Cerberus Network is a free membership service that EA has offered for early adopters of Mass Effect 2. Through the network players can already download several free DLC packs with more promised for the future. The Cerberus Assault Armor and M-22a Eviscerator Shotgun pack is just one example of this free content and will be available today starting at 12:00pm Mountain Time.
The content, as listed by the EA forums, is as follows:
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.
Mass Effect 2 was released on January 27th and has been rated M by the ESRB.
