There are several unlockable armor suits in Dead Space 3, including a throwback armor suit from the original Dead Space game, and even a cameo suit from Mass Effect. Here are all of the armor suits I have found to unlock so far. If you have more to add, please let me know in the comments.
Legends Suit – Beat the game on Casual, Normal, Survivalist, or Zealot difficulty
S.C.A.F. Deep Dig Suit – Collect every weapon part in the game
S.C.A.F. Flight Suit – To get the Flight Suit, you have to collect all 40 Artifacts in the game
S.C.A.F. Hostile Environment Suit – Complete the Dead Space 3 demo with 100% completion
N7 Armor Suit– Have a saved game from Mass Effect 3 on your hard drive or flash drive.
First Contact Suit — Included in the Limited Edition* version of the game in the “First Contact Pack” (Don’t have the limited edition? you may be able to find it on ebay)
Witness Suit — Included in the Limited Edition version of the game in the “Witness the Truth Pack” (Don’t have the limited edition? You may be able to find it on ebay)
It’s rumored that the limited suit codes will only work for a short amount of time. If you experience this, please let me know in the comments below.
If you’re looking for these suits on Ebay, always make sure the code you’re buying is for the correct version of the game.
