Abyssus is a brine-punk inspired roguelite FPS that debuted on Steam on August 12, 2025, and it has already won "Very Positive" player feedback. Developed by DoubleMoose Games and published by The Arcade Crew, the game features fast-paced, reflex-driven combat set in a chaotic underwater world. Players navigate 64 handcrafted levels shuffled into unpredictable layouts across four distinct zones, confronting challenging bosses and hordes of enemies. The arsenal includes eight unique weapons, each customizable with up to 45 mods, while "divine blessings" layer in additional bonuses to tailor your build.

The game supports solo play or online co-op for up to four players, with full controller and keyboard/mouse support. While critics praise its pace and design, noted rough edges include balance and co-op stability.

At launch, the game was priced at $24.99, but currently enjoys a 15% discount until August 19, 2025. SteamDB reports a steady player base, peaking at 4,629 concurrent users, suggesting strong and growing interest.
