There are quite a few unlockables and such in Dead Space 3.
I’ll be using this page to catalog everything I have found so far to help you out during the game.
Infinite Items Cheat
Dead Space 3 is a resource and money based game, so naturally you want to find the best and fastest ways to get these resources in the game.
There are a lot of different spawn points in the game for items. Most of these spawn points give you a random item, which will typically be money, a med pack, a stasis, or a random resource.
The easiest way to get infinite items is to take advantage of these spawn points and force them to respawn quickly.
Infinite Items Tip 1 – Look for an area where there are a lot of item lockers and boxes near where the game automatically saves. Collect all of the items, pause the game and choose Save and Quit, then reload your game and you’ll be back at the checkpoint to collect the items again. Near the end of Chapter 5 is a good example of this.
Infinite Items Tip 2 – Near the end of Chapter 8, keep an eye out for a shack that just has a bunk bed, a bench, and a generator in it. You’ll also see a random item on the ground inside of the shack. Pick up the item, go through the other door in the shack and close it. Open the door again and the item should have respawned.
Unlockable Power Weapons
There are two special power weapons that you can unlock in Dead Space 3.
These weapons can’t be crafted, and are only unlocked using these methods.
Devil Horns – Complete Classic mode to unlock the Devil Horns. This is a powerful and comedic weapon, similar to the Foam Finger in Dead Space 2, plus it looks pretty bad ass too. You just need to beat the game once to unlock Classic mode and most of the other unlockable modes.
Planet Cracker Plasma Cutter – You just need to have a saved game from Dead Space 2, and you’ll find the Planet Cracker Plasma Cutter at the first workbench.
Unlockable Armor Suits
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.
Unlockable In Game Armor Suits
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
Unlockable Armor Suits From Other Games
N7 Armor Suit– Have a saved game from Mass Effect 3 on your hard drive or flash drive.
Limited Edition Armor Suits
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)
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.
Unlockable Game Modes
There are five extra game modes that you can unlock in Dead Space 3.
The first four (Classic, Hardcore, New Game+, and Pure Survival) are unlocked simply by beating the game the first time on any difficulty.
Retro mode is unlocked by beating Hardcore mode.. have fun with that one.
Game Mode Descriptions
Classic Mode – Coop is disabled, you can only build classic weapons at the crafting bench, there are no cross hairs, and the difficulty level is set to Hard. Completing Classic mode unlocks the bad ass Devil Horns weapon.
Hardcore Mode – Death is permanent, so dying in this mode makes you start from the beginning (Diablo 2 style). You can save your game, but the save feature only really allows you to save and quit. Completing Hardcore mode unlocks Retro mode.
Pro Tip: Want to save your progress in Hardcore mode in case you die? Get a USB drive and copy your save game to it every time you save your game, that way if you die you can just copy it back and try again. This kind of defeats the purpose of Hardcore, but hey.. I’m ok with it if you are.
New Game Plus – You retain all of your resources and inventory from your previous game. You’ll also be able to find+3 Circuits and MK-II Overclocked Parts when playing through this mode as well.
Pure Survival Mode – Enemies no longer drop health or ammo (you’ll have to make it all at the crafting bench), and the difficulty level is set to Hard. Complete Pure Survival mode to unlock a MK-II Overclocked Parts set and a Mega Resources deposit.
Retro Mode – Retro mode adds a pixel filter to make the entire game look like old school games (Doom style.. yeah buddy!)
