Full disclosure, these were all pulled from IGN, they unlock some much needed inventory space as well as various other goodies. Enter them at http://www.defiance.com/en/my-ego/

I thought about putting all the codes in the post, but that's a lot, so here's a Google Doc file with all of them.

Also, anyone playing the PC version, feel free to add me, in-game name is Krakkn

Sure I do, only needed like 7 codes to get up to max EGO level, thingy, so thanks! :P
Are these codes that just work for everyone though? (I've heard there are codes that do, and then codes that don't)

These work for everyone, yeah. It's weird, because the site only goes up to 120 codes, but it'll take all 136 or whatever, I'm not sure what the extra give you, if anything, but I went ahead and added them anyway.

@krakn3dfx: Does seem a bit weird yeah, but anyways, thanks for getting me to 120! :P
Some needed unlocks and all that and, I guess, some titles to.. show off more text next to my name in game, I guess.
