Despite the game's official requirements stating the need for around 45GB of available storage, the 2016 reboot of Doom for the PC actually takes up just under 77GB of available space. And while this is still a small number compared to some other hard drive-heavy game installs, the Nintendo Switch version of Doom is apparently much lighter — something like 70% lighter, in fact.
According to a report from Go Nintendo, the Switch version of Doom only requires an initial download of just 13.4GB from the Nintendo eShop. However, any players who want to enjoy the game's multiplayer shenanigans — and really, who doesn't — will be required to download the multiplayer component separately, which means they'll need to make sure they have an additional 9GB of free space.
Basic math puts the total install size for Doom on the Switch at 22.4GB, a figure that's a whopping 54GB lighter than the PC version of the game. Where all that data went, we can't say for sure — maybe it was fired from a Gauss Cannon into the Martian atmosphere. And while 22.4GB will fit neatly onto one of the many 32GB Switch cartridges being produced by manufacturers, the game comes dangerously close to the 25GB of available storage on the Switch, given the extra space needed for things like firmware, updates, and various save files.
What this means is that Doom is very likely yet-another Switch title that will require players to pony up some extra dough to spend on expandable storage in the form of a microSD card, with the natural assumption that they'll have at least one other game or demo already installed on their console. NBA 2K18 was the first title we learned about that wouldn't fit in the Switch's on-board storage, and we learned just yesterday that the same is true for the Switch port of L.A. Noire, which weighs in at a total of 29 GB.
Fortunately for Switch owners, the margins of these storage limits are small enough to where players will only need a couple extra gigabytes in order to install any of these games, meaning any old 4 or 8GB microSD card they have lying around should be enough to complete the install. And, as we've pointed out before, it's relatively easy to use multiple microSD cards with the Switch — just don't expect to be able to load up all your favorite AAA titles on a single card unless you're willing to spend big bucks on a high-capacity card.
