If you’re rushing to install the hit new team-based MOBA before playing with friends, the first question you probably have is how many gb is deadlock for your specific device. Nothing kills pre-game hype faster than getting a “not enough storage” pop-up right as your squad is sending party invites, after all. I’ve been there too: I once deleted three old single-player games just to make space for a new release, only to realize I only needed half the space I thought I did. This guide breaks down exact file sizes across all platforms, plus extra space you’ll need for updates and patches down the line.
How Many GB is Deadlock Across All Supported Platforms
Deadlock’s install size varies slightly depending on your device and the version you’re running, but the base game follows consistent storage requirements across all official launch platforms. Keep in mind that these numbers are for the full launch version, and beta or test builds may have smaller or larger file sizes depending on active development changes.
PC (Steam/Epic Games Store): 76 GB minimum required space, with 90 GB recommended to leave room for future updates. The base install accounts for 72 GB, and the mandatory day-one patch adds an extra 4 GB of bug fixes and balance changes. If you opt into the public test server, you’ll need an additional 60 GB of space for the separate test build.
For Steam Deck users, the optimized portable build cuts out some high-resolution texture assets to save space, coming in at 68 GB for the base install. Steam Deck users need 75 GB of free space to avoid installation failures, as the handheld’s operating system reserves small amounts of space on the drive for system use. If you have a 64 GB base model Steam Deck, you’ll need to install the game on a microSD card to play.
On Xbox Series X and Series S, the install sizes differ to match each console’s performance capabilities. The Series X 4K build is 78 GB, while the Series S 1440p optimized build is only 62 GB. Xbox users should note that pre-load files take up extra temporary space during installation, so keep 100 GB free if you’re pre-loading to avoid getting stuck mid-install. If you use cloud gaming services like GeForce Now or Xbox Cloud Gaming, you only need ~100 MB of space for the launcher app, with no local storage required for the game itself.
Why Deadlock’s File Size Is Larger Than Many Similar MOBAs
If you’ve played other MOBAs like League of Legends or Dota 2, you might be surprised that Deadlock’s install size is 2-3 times larger than these older titles. That size difference isn’t unnecessary bloat, it’s tied directly to the game’s core design and the engine it runs on.
Deadlock is built on Valve’s Source 2 engine, the same engine used for Half-Life: Alyx and Counter-Strike 2. Source 2 engine’s advanced lighting and physics assets make up nearly 40% of Deadlock’s total file size. The game’s fully destructible map elements, dynamic weather systems, and high-fidelity character animations all require large asset files that add significantly to the total install size.
Another reason for the larger file size is that all character cosmetics and skins are included in the base install, rather than being downloaded separately when you unlock them. That means you won’t have to wait for downloads when you unlock a new skin or buy a battle pass, but it does add extra space upfront. I noticed that after playing for two weeks, my install size jumped to 82 GB just from saved replays and temporary cache files, so that’s something to watch for if you have limited storage.
The game also includes built-in cross-platform progression and replay tools that store local copies of your match history by default. These tools are great for reviewing your gameplay or sharing clips with friends, but they can add several gigabytes of extra data to your install over time if you don’t clear them out regularly.
Easy Ways to Reduce Deadlock’s Storage Footprint on Your Device
You don’t have to delete all your old games to make space for Deadlock, even if you’re right at the storage limit. There are a few simple tweaks you can use to cut down the install size without ruining your gameplay experience, and most only take a minute or two to complete.
- Delete old saved replays: You can turn off auto-save for matches in the settings menu, or manually delete replays older than 7 days to free up 2-10 GB of space instantly. Replays don’t affect your gameplay or progression, so you won’t lose anything important by removing them.
- Uninstall unused texture packs: If you’re playing on a 1080p monitor or a lower-spec device, you can remove the 4K texture pack via the game’s launcher settings to cut 15-20 GB off the total install size. You won’t notice any visual difference on smaller or lower-resolution screens.
- Clear temporary cache files: Every few weeks, go to your Steam/Epic library settings for Deadlock and select “clear local cache” to remove leftover patch files and temporary download data. This usually frees up 1-3 GB of space and can even fix minor performance issues.
You don’t have to sacrifice game performance to reduce the install size, as long as you only remove assets you won’t actually use. If you ever upgrade your monitor to a 4K display later, you can re-download the texture pack through the launcher in a few minutes. If you’re playing on console, you won’t have the option to remove texture packs, but clearing saved replays still works to free up extra space.
One more small tip: Turn off auto-download for cosmetic content in the game settings if you don’t care about skins or battle pass items. This will stop the game from downloading extra cosmetic assets every time a new patch drops, which can save you several gigabytes of space per update.
Common Storage-Related Deadlock Installation Errors to Avoid
Even if you have enough space for the listed install size, you might run into common installation errors if you don’t account for a few small details. Most of these issues are easy to fix once you know what causes them, so you won’t have to waste time troubleshooting right before a match.
The most common error is getting an “insufficient disk space” notification even when you have more than the listed 76 GB free. That happens because the launcher uses temporary storage space to download and unpack patch files during installation. You’ll need at least 20% more space than the listed install size to account for these temporary files, so aim for 90 GB of free space minimum if you’re installing on PC.
Never install Deadlock on an external HDD if you want fast load times, as the game’s large asset files will cause 2-3x longer load screens and occasional crashes. I ran into this exact issue when I tried to install Deadlock on my old external drive for a LAN party, and switching to my internal SSD fixed all the load time issues immediately. If you have to use an external drive, use an SSD instead of an HDD to avoid performance problems.
Another common error is corrupted install files from running out of space mid-download. If that happens, you don’t have to redownload the entire game. Just go to your launcher settings, select “verify local file integrity”, and the launcher will automatically replace any corrupted files without deleting the parts that downloaded correctly. This usually only takes 5-10 minutes, depending on your internet speed.
At the end of the day, knowing how many gb is deadlock for your specific device can save you a lot of frustration right before you jump into a match. The exact size will shift slightly as patches drop and new content is added, but sticking to the recommended storage limits will keep your game running smoothly for months to come. If you’re short on space, try the tweaks we listed earlier to cut down the install size without ruining your gameplay experience. Next time your squad asks if you have enough space to download the game, you’ll have the exact answer ready to go.
