Annulus System Requirements: PC Specs, Steam Deck Status & Mobile Availability
Annulus is a free-to-play dark fantasy tactical RPG from developer NIRVANA and publisher HONG KONG NIRVANA LIMITED, and it launched on 8 April 2026 for PC via Steam, the Epic Games Store, as well as iOS and Android. You play as the head of a mercenary regiment on the war-torn continent of Noviseth, collecting and cultivating mercenaries and weapons with unique attributes to build a fighting force capable of breaking the shackles of fate . Performance-wise, this is a lightweight Unity-based tactical game with genuinely modest hardware demands, but the official specifications vary across storefronts, and the game launched to mixed reviews with a 69 percent positive rating from early players .

What this means in practice: The minimum tier targets 1080p at 30 to 60 fps on low-to-medium settings, though NIRVANA does not specify a frame rate target on the store page. The Core i3 4th generation is a 2013 processor and the GTX 660 is a 2012 mid-range card, so this is hardware from roughly thirteen years ago. The 6 GB system RAM requirement is lower than the 8 GB floor most modern tactical games list, which reflects the game’s turn-based structure and grid-based combat. The 15 GB install size is moderate for a free-to-play tactical RPG. The broadband internet requirement is non-negotiable: Annulus is an online-only game with no offline mode. If you own a gaming PC from the last ten to twelve years with a dedicated GPU and 6 GB of RAM, you will clear this bar comfortably.
Recommended (Windows)
| Component | Requirement |
|---|---|
| OS | Windows 10 64-bit |
| Processor | Intel Core i5 4th generation or AMD Ryzen 5 2.8 GHz or higher |
| Memory (RAM) | 8 GB (Steam listing) or 16 GB (Epic Games Store listing) |
| Graphics | NVIDIA GeForce GTX 1060 or AMD Radeon RX 480 |
| VRAM | Not listed separately by the developer |
| DirectX | Version 11 |
| Storage | 32 GB (Steam listing) or 10 GB (Epic Games Store listing) |
| Network | Broadband internet connection required |
| Additional Notes | There is a significant discrepancy in the official recommended specifications across storefronts. The Steam page lists 8 GB RAM and 32 GB storage, while the Epic Games Store page lists 16 GB RAM and 10 GB storage. I cannot reconcile these figures without developer clarification. |

What this means in practice: The recommended tier targets 1080p or 1440p at 60 fps on high settings. The i5 4th generation is a 2013 processor and the GTX 1060 is a 2016 mid-range card. There is a notable discrepancy in the official recommended specifications between storefronts: the Steam page lists 8 GB RAM and 32 GB storage, while the Epic Games Store page lists 16 GB RAM and 10 GB storage . I am flagging this rather than papering over it, as it makes the recommended tier difficult to interpret. The GPU recommendation is consistent across both storefronts at a GTX 1060 or RX 480. If you have a gaming PC from the last six to seven years with a GTX 1060 or better and 8 GB of RAM, you will meet the lower of the two recommended specifications.
A Note on Conflicting Specification Listings
There are three different sets of system requirements circulating for Annulus, and it is worth understanding the differences. The Steam store page lists a minimum of Windows 7/8.1/8, Intel Core i3 4th gen, 6 GB RAM, GTX 660, and 15 GB storage, with a recommended tier of Windows 10, i5 4th gen, 8 GB RAM, GTX 1060, and 32 GB storage . The Epic Games Store page lists the same minimum but a recommended tier of 16 GB RAM and 10 GB storage, which contradicts the Steam figures . A Steam news post from the January 2026 playtest listed an entirely different minimum specification with 8 GB RAM, a GTX 750 Ti, and 13 GB storage , which likely reflects an earlier build of the game. I am using the current Steam store page as the authoritative source for the minimum tier, as it represents the shipping version of the game, but readers should be aware that the recommended figures are inconsistent across official storefronts.
A Note on VRAM and System RAM
NIRVANA does not publish a separate VRAM figure for either tier, which is a gap in the official information. The GTX 660 shipped with 2 GB of VRAM, and the GTX 1060 shipped with 3 GB or 6 GB, so the practical VRAM floor is likely 2 GB for the minimum and 3 GB for the recommended tier. Annulus is a turn-based tactical game with an isometric camera perspective, grid-based combat, and stylised dark fantasy environments . This is not a texture-heavy or geometry-intensive rendering approach, and you will not encounter VRAM bottlenecks at 1080p on any dedicated GPU from the last decade. The 6 GB system RAM minimum is the more relevant constraint, and the 8 GB recommendation is the practical comfort target. Do not upgrade your GPU beyond a GTX 1060 for this game.
PC Performance Reality: Read Before Buying
The official specifications describe a lightweight tactical game, but player reviews reveal a game with significant technical and design issues beyond raw hardware requirements. ScreenRant’s launch coverage reported that Annulus holds a 69 percent positive review rating from early players, with criticisms focused on localisation quality, UI design, graphics, and gacha mechanics . One user quoted by ScreenRant stated, “finally, a strategy game where positioning really matters,” suggesting that the tactical core has merit despite the surrounding issues . ScreenRant also noted that the game “may occasionally feel like Baldur’s Gate 3,” though “it is intended to be a game of its own” . The game contains pre-generated AI content for art assets, story texts, and UI assets, created using Midjourney and GPT, though the developer states that all AI-generated content has been “revised, polished, screened, and copyright-verified by a professional team” . If you are sensitive to AI-generated content in games, this is worth knowing before you download.
PlayStation 5, Xbox Series X|S, and Nintendo Switch 2: Not Available
Annulus has no PlayStation 5, Xbox Series X|S, or Nintendo Switch version. The confirmed platforms are PC, iOS, and Android only . IGN’s game page confirms the platforms as “iOS, Android, and PC (Steam)” , and Gamereactor’s release coverage lists the game as arriving on “Android, iOS, and PC on the 8th of April” . The Steam store page explicitly states “No Mac or Linux clients are currently available” . If you play primarily on a console or a Mac, you cannot access Annulus.
Steam Deck
| Component | Requirement |
|---|---|
| Compatibility | Not confirmed by Valve as of my verification date. No official Verified or Playable rating has been published. |
| Performance | The game’s minimum specifications are within the Steam Deck’s capabilities on paper, but the broadband internet requirement and gacha-based monetisation suggest a live-service structure that may not translate well to handheld play. |
| Additional Notes | The 15 GB install size is manageable. Steam Deck users would play through Proton, as there is no native Linux build. Check current community reports before purchasing for handheld play. |

What this means in practice: Annulus has no confirmed Steam Deck compatibility rating from Valve as of my verification date. The game’s 6 GB RAM minimum and GTX 660 minimum GPU are within the Steam Deck’s capabilities on paper, but the broadband internet requirement and gacha-based monetisation suggest a live-service structure that may not translate ideally to handheld play. The 15 GB install size is manageable. There is no native Linux build, confirmed by the Steam store page’s note that “No Mac or Linux clients are currently available” , so Steam Deck users would need to run the game through Proton. If you own a Steam Deck and want to play Annulus, check current community reports before committing, as the game’s online-only structure and monetisation model are more significant considerations than its hardware requirements.
iOS and Android

What this means in practice: The iOS and Android versions launched on 8 April 2026 alongside the PC version . PocketGamer’s coverage described the game as a “graphically lush tactical RPG” that is “now available on iOS and Android,” and noted that players “explore the continent of Novisses as a mercenary captain battling for coin” . NIRVANA has not published separate mobile system requirements on the App Store or Google Play listings, so I cannot state confirmed device compatibility. The game’s free-to-play model with gacha mechanics is consistent across all platforms . If you own a reasonably modern iOS or Android device, the game should run, but check the App Store or Google Play listing for specific device compatibility before downloading.
Price and Monetisation
Annulus is free-to-play on all platforms . The game launched on 8 April 2026 and is described as “free to keep forever” once added to your library, according to ScreenRant’s launch coverage . However, the game includes gacha mechanics and optional in-game purchases, which were among the criticisms raised by early players . There is no subscription required to access the base game.
Reception and Review Scores
Annulus holds a 69 percent positive review rating on Steam from 88 player reviews as of ScreenRant’s launch coverage, giving it a “Mixed” overall rating . The most common criticisms are the localisation quality, UI design, graphics, and gacha mechanics, while the most consistent praise is for the tactical combat system, with one user stating “finally, a strategy game where positioning really matters” . ScreenRant noted that “multiple users mention that it took some time to get used to the mechanics in Annulus, but that once they click, the free RPG on Steam becomes an amazing title to spend your time with” . The game holds a “Mixed” overall rating on Steam with 509 total reviews, according to the Steam store page . Metacritic lists the game with no critic reviews as of my verification date .
Final Verdict: Can Your PC Run Annulus?
Yes, almost certainly. Annulus is one of the more accessible free-to-play tactical RPGs of 2026 on PC. The minimum spec asks for an Intel Core i3 4th generation, 6 GB of RAM, and a GTX 660, which is hardware from 2012-2013. The 15 GB install size is moderate, and the broadband internet requirement is non-negotiable: Annulus is an online-only game with no offline mode. If you own a gaming PC built in the last ten to twelve years with a dedicated GPU and 6 GB of RAM, you can run this game at 1080p and 30 to 60 fps without difficulty.
The recommended tier contains a significant discrepancy between storefronts: the Steam page lists 8 GB RAM and 32 GB storage, while the Epic Games Store page lists 16 GB RAM and 10 GB storage . The GPU recommendation is consistent at a GTX 1060 or RX 480. I cannot reconcile the RAM and storage figures without developer clarification, but if you have a gaming PC from the last six to seven years with a GTX 1060 or better and 8 GB of RAM, you will meet the lower of the two recommended specifications. Do not upgrade your hardware beyond the recommended tier for this game.
