Dominus Gladiatus Steam: Price, Requirements and Install

Dominus Gladiatus is available on Steam right now for $15.99, a 20% launch discount off its $19.99 list price that ends on 19 November 2026. Search the official Steam store page, add it to your cart, and Steam handles the rest — the game released on 5 November 2026 and is a Windows-only gladiator management sim from Brain Seal Ltd, published by PlayWay S.A. This page covers the price, system requirements, what the Steam release includes, and the game's current state after its first week of patches.

Price and how to buy

The base price is $19.99, discounted to $15.99 by the "Introductory Offer" that runs until 19 November 2026, checked on 2026-11-08. Regional pricing applies elsewhere — on 2026-11-08, SteamDB listed CLP$ 9,599 in Chile and Rp 119,999 in Indonesia at the same 20% discount, so the exact figure depends on your store region.

The store page also lists fifteen bundles that include Dominus Gladiatus alongside other PlayWay titles, each applying a 10% bundle discount on top of individual discounts. Three examples:

If you only want this game, buy it standalone at $15.99 — the bundles only pay off if you actually want the second title.

System requirements

The requirements are very modest. The official Steam page lists:

The recommended tier only repeats that a 64-bit processor and operating system are required — no higher specifications are listed. In practice the download is small: SteamDB records the depot at roughly 1.97 GiB on disk with a download of about 463 MiB, so it runs comfortably on nearly any DX11-capable PC from the last decade. A free demo is also available on the same store page if you want to test performance before buying.

What the Steam release includes

The Steam release ships as a single-player game with these platform features: Steam Achievements (23 total), Steam Cloud, Family Sharing, and full controller support including Xbox, DualShock (USB) and DualSense (USB) controllers. The game is Steam Deck Verified, and the developers implemented native Deck support during the demo phase in October 2026.

Fifteen interface languages are supported, including English, French, German, Spanish, Japanese, Korean, Russian and both Chinese variants. English is the only language with full audio and subtitles; the others are interface-only.

Content-wise, the developer describes it as a brutal gladiator management simulator: you run a gladiator school (a Ludus), recruit fighters at the slave market, train and equip them, manage morale, injuries and fatigue, and watch auto-battler arena duels play out against five rival Domini in a tournament. Steam tags include Gore and Violent, and the mature content description mentions blood and decapitations.

Current state: launch patches and updates

The game launched on 5 November 2026 and has already received two major updates, so the version you install today is well past the day-one build:

• Day 1 Update (5 November 2026): winning the Grand Tournament no longer ends your save — you can continue with batches of arena contracts, retire as Dominus whenever you like, and get 2× game speed (hold right mouse button or RT), ultrawide support, and improved tutorials.
• Patch #2 (7 November 2026): added two new modes — the Blood Games, a 90-day, 22-fight gauntlet ending in a 4v4 Colosseum final, and the Provincial Games, a shorter 40-day tournament for newer players — plus more brutal finishers, deadlier beasts, and menu improvements.

Player reception was Mixed: 56% of 203 user reviews are positive as of 2026-11-08 on the Steam store page. SteamDB's chart recorded an all-time peak of 1,221 concurrent players on launch day, with several hundred playing at any given time during the first week. The developers are actively responding to feedback on the Steam Community hub, so expect further balance patches.
