Mycopunk vs Abyssus: Brinepunk Runs vs Persistent Grid Builds

Two Indie Co-op Shooters, Two Philosophies

Abyssus and Mycopunk are close cousins by genre: fast first-person PvE shooters built around online co-op for up to four players, with randomized elements layered over responsive gunplay. Abyssus, from DoubleMoose Games and published by The Arcade Crew, sends a team of brinepunk explorers into a sunken kingdom to fight mutated guardians over a powerful substance called brine. Mycopunk, from Pigeons at Play and Devolver Digital, sends robot employees onto fungal planets to do dangerous corporate work.

Both are PvE-only — no PvP in either. Both reward constant movement and aggressive positioning. And both entered a crowded co-op shooter market by leaning on one distinctive system rather than a checklist of features. Where that system lives — in the run or in the build — is what separates them.

TL;DR Comparison

Setting and Tone: Corporate Fungal Apocalypse vs the Sunken Deep

Neither game is trying to be grim. Mycopunk's humor comes from satire — you play expendable robots hired by the SAXON corporation because nobody else would take the job, and the writing leans into that joke constantly. Abyssus builds its personality through aesthetic instead: a lush, hand-crafted underwater world of ancient ruins, brine-powered weaponry and corrupted sea denizens. It is the more atmospheric of the two; Mycopunk is the funnier one.

The settings also shape mission structure. Abyssus sequences hand-crafted levels into procedurally ordered runs, so each attempt moves through familiar rooms in new arrangements. Mycopunk uses short objective missions on fungal planets — no procedural generation, but escalating threat levels and enemy variety keep repeat visits interesting. If your group values visual atmosphere, Abyssus has the edge; if you value comedy and a clear loop, Mycopunk does.

Builds: Blessings and Mods vs the Hex Grid

Abyssus' build depth comes from combination. You pick a loadout before the run, then layer in-run weapon mods and divine blessings — elemental and mystic effects that stack toward crowd control, damage or survivability. The mod pool is broad (its arsenal is small but heavily customizable), and the meta progression between runs gradually widens your tactical options. Like most roguelites, the joy is in stacking synergies the run offers you.

Mycopunk's depth comes from craftsmanship instead. Every weapon carries its own hexagonal 7x7 upgrade grid where Tetris-shaped pieces must be placed, and since 1.0 stat values scale with pattern size — so placement is a genuine spatial puzzle. Your build is never taken away: it persists, gets refined, and gets torn down voluntarily when a patch changes the math. Our best builds guide and weapons tier list exist because players actively argue about optimal grids — that argument is the hobby.

There is also a character-side difference worth noting. Neither game has traditional classes: Abyssus builds identity through suits, skills and loadouts, while Mycopunk's five employees — Wrangler, Bruiser, Scrapper, Glider and the 1.0-added Mycologist — differ in movement kits, with combat identity coming from weapon grids. Squads in both games compose themselves around gear, not roles.

Sessions, Failure and Where to Spend Your Money

Structurally, Abyssus is a run game: a session has an arc, builds reset when it ends, and only meta progression carries forward. That makes it ideal for defined play windows and gives each attempt stakes. Mycopunk is mission-based — shorter chunks, but nothing you built is ever lost, and a failed mission costs time rather than power. For weeknight squads with unpredictable schedules, persistent progression is the more forgiving framework.

Platform and value differ too. Abyssus launched on PC in 2025 and later reached PS5 and Xbox, with Game Pass availability on the Xbox side — a cheap way for subscribers to try it. Mycopunk's 1.0 launch on October 20, 2026 hit PC and PS5 simultaneously at $14.99, with day-one placement in the PS Plus October catalog (details) and modest PC requirements (official specs). Both are friendly to budgets; check which subscription you already hold.
