Its too late. You had to preorder it from play or gamestop.How to get Terminus Armor? (Mass effect 2)?
Those codes don't come inside the packaging for the game. When you picked up the game the store should have given you the codes, often-times you actually have to ask for them yourself. However it looks like it might be too late to get the codes now.How to get Terminus Armor? (Mass effect 2)?
I would take it to gamestop and tell them that they messed up.
