Dead Space is considered one of the best modern survival horror games and one of the best examples of sci-fi horror in games. The 2023 remake was a mostly faithful remake of the original game, with all the scares and horror of the original. It gave the classic a fresh coat of paint, a modern feeling shooting, and more seamless transitions between different parts of the Ishimura ship that the game takes place on. The remake also presented an opportunity for anyone who was too scared to finish the original Dead Space another chance at making it to the credits.
Of course, Dead Space (2023) isn't perfect; no game truly is, so modders have gone ahead and taken matters into their own hands. There isn't a massive selection of Dead Space mods, but we have gathered three that can improve your experience with Dead Space, especially on a second playthrough.

3 Dead Space 2023 New Game Plasma Cutter Only
Made by Snaz89
The Dead Space 2023 New Game Plasma Cutter Only mod by Snaz89 on Nexus Mods makes modifications to the new game plus mode in Dead Space to keep the challenge of a first run without losing collectible progress. They describe it as a new game plus mode where you start with just the Plasma Cutter and first suit, just like you would on a fresh save file. The logic here is that most of the fun of playing Dead Space (2023) and many horror games like it is the tension of not having the firepower to blow through enemies, forcing you to be smart and safe with your choices. The new game plus mode lets you keep all of your equipment normally, making the game much breezier the second time. If you like doing complete runs but don't want an easier time because of New Game Plus, this mod has you covered.
2 Dead Space in the Dark - Reshade
Made by Mickterminator30

Source Nexus Mods
The Dead Space in the Dark - Reshade mod by Mickterminator30 is for the horror sickos who just can't get enough adrenaline-pumping scares. This mod doesn't add new monsters or jump scares, but it does make the interior of the Ishimura much darker. It's a lighting and brightness mod that takes the game's default lighting, which is pretty dark by default, to be even darker. Mickterminator30 said in their post that they feel like the default brightness in Dead Space (2023) is too bright and blotchy, which is why they made a mod all about making it darker. They said "the Ishimura's overall sense of dread could be improved", a sentence that some people probably strongly disagree with. If you are a hardcore horror game fan, this mod is perfect for you, as it ratchets up the intensity of Dead Space (2023) by making it truly impossible to see the horrors before it's too late.
1 Zealot Hardcore Mode

Dead Space remake gameplay
The Zealot Hardcore Mode made by bigbullet3 on Nexus Mods is for people who love a challenge. Difficulty mods are fairly popular, especially among a group of gamers who are always looking for an experience that truly challenges them. That's why bigbullet3 made this mod, which makes the Impossible difficulty in Dead Space (2023) more like the Zealot difficulty from Dead Space 2.
"I made this because I felt that the Impossible mode in the remake was much easier than I remember the originals being." - bigbullet 3 on Nexus Mods
The mod specifically targets Isaac's defense and inventory slots. The defense is lowered across the board, making it much easier to die, with enemies like Exploders always killing in a single hit. It also makes it so 12 inventory slots is the max you can have, which is less than the max in Dead Space (2023). That change is meant to make the survival aspect of the survival-horror game more intense, forcing you to pick and choose what items you hold and how often you should use them. If you love a challenge, this mod should satisfy.
