New Doom-inspired co-op roguelite FPS debuts on Steam with "Very Positive" reviews and launch discount
When Abyssus surfaced on Steam on August 12, 2025, it brought its own unique brine‑punk style to the roguelite FPS genre. It's developed by DoubleMoose Games and published by The Arcade Crew. In Abyssus, players are in a chaotic, underwater world where survival hinges mostly on quick reflexes, customizable gear, and divine power.
From the moment you start, you’ll be greeted by handcrafted levels shuffled into unpredictable patterns - 64 in total - each full of enemies and topped by challenging bosses across four distinct areas. The arsenal has eight unique weapons, each tweakable with one of 45 possible mods, and 'divine blessings' add more flair to your build as you progress through the runs.
The game supports up to four-player online co-op, but solo play looks pretty self-sufficient too. Reviews across the web are very favorable. Its fast pace has drawn comparisons to Doom, yet the reviews also mention that there’s more than just frenetic action here: mobility is key, with skills like double jump and dash shaping your movement through different levels. You can switch between keyboard/mouse and controller, since the game has full support for both.
As for the numbers, SteamDB reports around 2,725 concurrent players at the last check, with a peak of 4,629 on the day it launched. Overall, user reviews have skewed positively - 85% of 548 reviews show "Very Positive" ratings by now. Not only player reviews are positive - critics have also praised its pace and design, though many mention balancing rough spots and multiplayer hiccups. Metacritic has given Abyssus a mixed-to-average rating of 73, pointing out consistency and polish issues.
At launch, the base game cost $24.99 but is currently discounted by 15% - bringing it down to $21.24 until August 19, 2025. There are extra sides like the Brinehunter Pack (includes helmet, emote, frame) and the original soundtrack.
Abyssus looks like a solid bet for fans of roguelite shooters, and the game's concurrent player base looks promising if you're looking to try it out for yourself. Check the game page on Steam store here.
