But if you buy the game new, the network, armor and Zaeed comes free. The downside is that you have to buy the Cerberus Network to get it if you didn't buy Mass Effect 2 new. It gave you 10 % shield, 10 % health plus 10 %in heavy weapon ammo boosts. I initially felt that the best armor for Mass Effect 2 on the Insanity difficulty level was the Cerberus Assault Armor.
