sadly this game needs more than codes to save it. The worst part about this game is the MP actually is pretty fun... The SP game half way in gets undeniably bad. Horde mode 100% should have been offered up from the start. I think they should release that for free...might help them save what little face they have now.
They need to hand out a copy of Borderlands 2 and some gold keys to make up for the shittyness of Aliens. That only makes sense if you want some gold keys :)
Why not spit in our faces while you're at it.
