The latest reported figures put ARC Raiders at 47.4 GB on PC and 47.5 GB on Xbox Series X|S, based on Microsoft Store catalogue data last checked August 28, 2026. Those are dated estimates, not verified October 2026 sizes: a later game update was listed on September 29. An exact current PS5 size was not established. For the number that applies to your copy, check the platform’s download screen before clearing space or starting the install.
ARC Raiders install size by platform
| Platform | Best available size information | What to keep in mind |
|---|---|---|
| PC | 47.4 GB, according to Game Idealist using Microsoft Store catalogue data last checked August 28, 2026 Game Idealist. | This is a third-party catalogue-derived estimate, not an official Steam storage requirement. Steam’s listing does not state a storage figure in the page text available here Steam. |
| Xbox Series X|S | 47.5 GB, according to Game Idealist using Microsoft Store catalogue data last checked August 28, 2026 Game Idealist. | It should not be treated as a verified October 2026 size; the tracker notes patches can add to a listed game size. |
| PS5 | No current installation-size figure was stated in the official PlayStation listing reviewed PlayStation Store. | The listing confirms a PS5 version and online-only play, but not how much storage the install needs. |
| GeForce NOW | No local install-size figure applies: the official site lists GeForce NOW as an available platform ARC Raiders. | Cloud streaming is different from installing the game on a PC or console. Check the service for current device availability and terms. |
Why the reported numbers may be out of date
The PC and Xbox estimates were last checked August 28, 2026. Embark’s official site subsequently listed Store Update 1.48.0 on September 29, 2026 Embark. Because updates can change a game’s files—and the size tracker itself warns that patches may add to the listed size—the August figures are useful for planning, but they do not establish the exact size today.

Also, “download size” and “installed size” are not necessarily the same measurement. The available listings do not establish ARC Raiders’ current download size, installed size, or any temporary free-space requirement during installation or updating. Do not assume the reported GB figures cover all three.
How to check the size before installing
- Open the game’s listing or download screen on your platform. Use Steam or the Epic Games Store on PC, the Xbox Store on Xbox Series X|S, or the PlayStation Store on PS5.
- Check the displayed download or storage requirement. Read the platform’s current figure rather than relying on an older catalogue estimate.
- Confirm available space before beginning. If the platform shows a separate install or update requirement, use that figure; the dated estimates above do not establish a safe additional-space allowance.
Does the Steam requirements page give a storage figure?
No storage-capacity number appears in the Steam listing text available here. Steam does list minimum PC requirements: Windows 10 or later (64-bit), an Intel Core i5-6600K or AMD Ryzen R5 1600 processor, 12 GB RAM, and an NVIDIA GeForce GTX 1050 Ti, AMD Radeon RX 580, or Intel Arc A380 graphics card Steam system requirements. These hardware requirements do not tell you how many gigabytes the game currently occupies.

Where ARC Raiders is available
The official site lists Steam, Epic Games Store, PS5, Xbox Series X|S, and GeForce NOW ARC Raiders platforms. It describes cross-platform social play across PlayStation, Xbox, and PC. Platform availability does not mean the game has an identical local install size everywhere; use the download screen for the platform you intend to play on. The PlayStation listing also specifies online-only play and says online play is required PlayStation Store.
