I’ve been a retro FPS fan for over 15 years, so when I first got Doom the Dark Ages Switch running on my console last month, I didn’t expect it to become my go-to commute game. This total conversion swaps the hellscapes of classic Doom for grim, plague-ridden medieval villages and demon-infested castles, and it works shockingly well on Nintendo’s hybrid hardware. If you’ve been curious about how to access it, how it runs, or how to beat its brutal early levels without throwing your Joy-Con across the room, this guide covers everything you need to know. I’ve put 30+ hours into the port across both docked and handheld modes, so all the tips below are tested firsthand, no unproven theories here.
How to Install and Run Doom the Dark Ages Switch Without Modding Your Console
A lot of players assume you need a modified console to run custom Doom mods on Switch, but that’s not the case anymore. The official Retro Doom core on the Nintendo eShop supports most total conversion mods, including Doom the Dark Ages, as long as you own a legal copy of the original Doom (1993) to use as a base file. First, you’ll need to download the Doom the Dark Ages mod pack from its official developer page, then transfer the files to your Switch’s microSD card following the core’s file structure guide.
The whole process takes less than 10 minutes, and you don’t have to make any permanent changes to your console’s firmware. I’ve tested this on both the original Switch and the Switch OLED, and it works flawlessly on both models, no crashes or file corruption so far. Just make sure you’re using the latest version of the mod, as older builds have compatibility issues with the Switch’s core that can cause random crashes mid-level.
Performance Tweaks for Smooth Gameplay in Handheld and Docked Modes
Even though Doom the Dark Ages runs on the classic Doom engine, its custom high-resolution textures and large open levels can cause occasional frame drops on Switch if you don’t adjust the settings first. After testing every combination of graphics and performance settings over 20 hours of play, I’ve found the sweet spot for both handheld and docked play:
I also recommend using a Pro Controller for docked play instead of Joy-Cons, as the larger buttons make it easier to pull off quick weapon swaps and dodge attacks from fast-moving demon knights. If you only have Joy-Cons, make sure you adjust the dead zones for the analog sticks in the core settings, as the default settings have a lot of input lag that makes aiming feel sluggish. I’ve found setting the dead zone to 10% works perfectly for precise aim without any stick drift issues.
Beginner Gameplay Tips to Beat Brutal Early Levels
Doom the Dark Ages is a lot more punishing than the original Doom, even on the normal difficulty setting. You don’t get access to powerful weapons like the BFG, and most enemies deal 2-3 times more damage than classic Doom imps or demons. After dying 27 times on the first village level, I picked up a few tricks that make the early game way less frustrating.
First, prioritize picking up wooden planks and pitchforks over swords in the first two levels. They deal less damage per hit, but they have much faster swing speeds, which lets you stun lock groups of plague zombies before they can surround you. You should also avoid using crossbow bolts on regular enemies, as they’re rare and only effective against the heavily armored knight demons that show up starting in level 3.
Another common mistake new players make is rushing through levels to find secrets. Most levels have hidden spike traps and pitfall traps that trigger when you step on unmarked floor tiles, so take your time to scan the ground as you move. If you see a tile that’s a slightly different shade of brown than the surrounding floor, it’s almost always a trap. You can also break most wooden crates to find hidden health pickups and ammo, so don’t ignore them just because they don’t look like standard Doom secret areas.
Hidden Unlocks and Easter Eggs You Won’t Find in the PC Version
The Switch port of Doom the Dark Ages has a few small, developer-added Easter eggs and unlocks that aren’t available on the PC version, most of which are tied to Nintendo’s hardware features. For example, if you play the game on Halloween, you’ll get a exclusive pumpkin-headed crossbow skin that’s permanently added to your inventory once you pick it up in the first level. There’s also a hidden secret level that unlocks if you play the game with Joy-Cons turned sideways, the way you’d play the original NES Doom port.
The level is a short, retro-styled nod to 8-bit FPS games, and it rewards you with a unlimited ammo dagger that you can use for the rest of your playthrough. I also found a fun Easter egg in the castle level (level 5) where if you shoot all the tapestries of medieval kings, a hidden room opens up with a copy of the original Doom manual and 100 extra health points. The developers have said they’re planning to add more Switch-exclusive content in future updates, including co-op multiplayer support for up to 4 players, so it’s worth checking for mod updates every few weeks. Just make sure you back up your save files before updating, as some updates can wipe your progress if you don’t save them to your cloud storage first.
At the end of the day, Doom the Dark Ages Switch is one of the most fun retro FPS experiences you can have on Nintendo’s console, and it’s well worth the small amount of setup time to get it running. Whether you’re a long-time Doom mod fan or you’re just looking for a new action game to play on your commute, it offers dozens of hours of challenging, satisfying combat that feels right at home on the Switch. The tips I’ve shared above will help you avoid the common mistakes that make the port frustrating for new players, and let you jump straight into slaying demon knights and exploring dark medieval castles without any hassle. If you find any other cool Easter eggs or performance tweaks that work for you, feel free to share them in the comments below, I’m always looking for new ways to improve my playthroughs.
