When you activate your Cerberus Network code, it entitles you to some free add-ons for your game. These add-ons are:
Normandy Crash Site : Revisit the planet where the Normandy SR1 is located.
Zaeed Massani : Zaeed served in the Alliance military before building a reputation as one of the deadliest guns-for-hire in the Terminus Systems. For 20 years he waged war for profit, but now he wishes to retire from his life of bloodshed and mercenary work. Download Zaeed and his mission on planet Zorya and then utilize his lethal skills to eliminate the Collector threat.
Firewalker Pack : Download the Firewalker pack and gain access to 5 new missions featuring the Hammerhead. The Hammerhead is a heavy assault vehicle that hovers over the battlefield at up to 120 kilometers per hour and features a guided missile system ensuring accuracy even during aggressive maneuvering.
Arc Projector : The Arc Projector is capable of discharging a high-voltage electrical attack to multiple targets in the battlefield. As the lightning-like bolt hits its first target, a sophisticated auto-targeting system paints succeeding targets with an ionization laser, allowing the electricity to arc between them. Careful aiming will also allow the user to arc shots to nearby explosives as well. An entire enemy squad can be dropped with a careful pull of the trigger.
Cerberus Assault Gear : Designed with three things in mind: shields, thick armor, and auxiliary ammo packs, the Cerberus Assault Armor is given to shock troopers who are expected to turn the tide of battle against forces that would decimate normal soldiers. Additionally, the M-22 Eviscerater Shotgun comes standard issue. Lethal at close range, the Eviscerater Shotgun is a favorite among Cerberus operatives who like to get up close and personal with their foes.
