Dead Space

This achievement is for completing the entire campaign only using the Plasma Cutter. It is easily doable on medium difficulty and those who are familiar with Dead Space could do it on Impossible difficulty without any real issues.

However, there are a few tips to consider:

You can pick up other guns throughout your playthough, just be sure NOT to fire them. To be safe, don’t even equip them - return any other weapons and upgrades to the safe to avoid any mistakes and free up space in your inventory.

Use of Stasis, Kinesis and Melee does not affect your playthrough.

Make best use of your inventory. Only stock Medkits, Plasma ammo and a Stasis pack or two. Sell the rest back to the store for credits. The game is intuitive and will only tend to drop ammo for your equipped weapons, reducing pressure on purchasing ammo. But, if you want to farm credits, it’s worth keeping the Force Gun equipped whilst remembering not to use it (probably best not to do this).

Use your power nodes solely for Suit and Plasma Cutter upgrades only, they’re no good on other weapons that you can’t use. There are enough Power Nodes in the game to max out the Plasma Cutter and your Suit on one playthrough if you take the time to collect them.

At the start of the game, grab yourself the HP Suit upgrade using a Node and then just focus on the Plasma Cutter upgrades - further Suit improvements are not necessary until Chapter 4 onwards. This also applies to impossible difficulty but feel free to be cautious, it’s better than taking an unnecessary risk.

That said - don’t neglect your Suit, especially later in the game. Upgrade it accordingly so that you can continue with its HP upgrades, but air and other parts are not essential.

Be sure to find the 3 Plasma Cutter upgrades because having it maxed out will make the final levels easier:

- Chapter 2: Intensive Care - Ammo Capacity (after destroying the barricade, it is in the Clinic).
- Chapter 3: Collision Course - Heat Pack (it’s available in the store for 11K credits from this point on).
- Chapter 8: Search and Rescue - Weighted Blades (in the maintenance room just before you take on the Leviathan Remnant).

Edit (November 2023): Credit to Zack R T who advised that the first and second upgrades have been rotated. I have no idea why MOTIVE did that but I can confirm following a recent play though. Guide amended.

Importantly, know your enemies. The Plasma Cutter can deal with almost anything but 4 enemy types can cause you issues, mostly because they’re a drain on your ammo but they can catch you out. These are:

- Swarms (the creeps that jump your back).
- Pregnants (the ones that drop Swarms if you shoot them in the Torso).
- Dividers (the ones that break down into heads or other individual body parts).
- Guardians (stuck to the walls and spit out single, immobile lurkers). Don’t get close until dead!

Quite often there will be an explosive red canister or generator in the immediate vicinity that can dispatch them in one (not the Pregnants or Dividers when whole, only when they are broken into smaller enemies - using a canister on these whole only opens them up).

Visual Guide.

Overall, this achievement is not hard, but it is possible to make a mistake, therefore I would like to re-emphasise point 1, DO NOT even equip other weapons, put all unrelated items into the store and sell unwanted items to reduce the risk of a mistake.

Edit: Just to Clarify, I am not sure if this can be done on a New Game Plus, as I did it on my first playthrough. I would be surprised if you couldn’t though, providing you do not use any other weapon. If anyone would be so kind to comment and advise, I’ll update accordingly. Thank you.

Good luck!

Not sure what the parameters are for this achievement but seeing how there isn't any info out yet, I'll just state that I accidentally picked up some other guns during the campaign, but paused and backed out to the menu during the animation and loaded into a checkpoint before picking it up. Still got the achievement just fine for any of those that may have worries with it happening.

(I also didn't pick up any upgrades for the other guns but I think that was me being overkill and not wanting to rage if it somehow voided the achievement 😅)
