Abyssus is already a tense and atmospheric roguelike when played solo, but its true potential shines when you bring friends into the mix. The game supports up to four players, turning expeditions into chaotic and strategic co-op dives where coordination matters as much as firepower. This guide covers everything you need to know about setting up sessions, working as a team, and making the most of multiplayer in Abyssus.
How to Set Up Abyssus Multiplayer and Co-Op Lobbies
Multiplayer in Abyssus is accessed through the Transmitter, which you can find just to the right of your tent in the hub camp. From here, you can either host or join a session:
- Session Name – Create a unique title so friends can easily find your lobby.
- Max Players – Choose between 2 to 4 total players.
- Password Protection – Add one if you want to keep your lobby private.
- Visibility – Allow random players to discover your session, or keep it invite-only.
If you’re hosting, it’s best to let the player with the strongest PC setup run the session for smoother performance and fewer connection issues. When you open the Transmitter, you can also use the Session Browser to search for active lobbies. If you join another player’s session, you’ll be transported to their camp before starting the expedition.

Does Abyssus Support Crossplay?
Currently, Abyssus is only available on PC. That means there’s no crossplay with other platforms, at least for now. Should the developers expand support in the future, cross-platform multiplayer could open up, but as of now, the experience is PC-exclusive.
Multiplayer Tips and Team Strategies
While multiplayer adds more enemies and complexity, it also gives you access to more weapons, abilities, and team synergy. Here are some key strategies to keep in mind:
1. Communicate Aspects and Charms
Each player will encounter Charms and Aspects that enhance specific weapons or abilities. Not all upgrades are useful for every build. Talk with your team before claiming items so they go to the player who benefits the most. For example, a Charm boosting shotgun reload speed is wasted on someone running long-range rifles.
2. Create Unique Weapon Builds
Ideally, each teammate should bring a different primary weapon to maximize flexibility. A balanced squad can adapt to all enemy types and bosses more effectively. That said, comfort trumps variety—don’t force yourself into a weapon you dislike just for diversity. Play what you’re best with, but consider the team’s overall coverage.

3. Divide and Conquer Objectives
Many rooms in Abyssus feature tasks like charging pylons or destroying crystals in addition to fighting enemies. In these rooms, enemies will continue spawning until the objective is complete. Divide responsibilities among the squad so some players handle the mission task while others keep the waves under control.
4. Focus Bosses and Weak Points
In most boss rooms, defeating the boss instantly clears the remaining enemies. Bosses usually have glowing weak points near their cores—make these your focus, and only clear grunts if you need charges for abilities.
5. Mobility and Positioning
Always keep moving. Rotate between high ground and low ground, avoid predictable backward kiting, and use dash or double-jump to reposition quickly. With four players in the arena, mobility prevents bottlenecks and allows the squad to support each other more effectively.
6. Mind the Fall Damage
Despite being set underwater, Abyssus includes fall damage of around 5–10 HP, which can easily swing a close fight. You can negate fall damage with a last-second mid-air dash, so practice this trick to stay safe in vertical arenas.
7. Heal and Loot Smart
Before burning healing syringes, scan the arena. After bosses or between rooms, free heals may drop on the ground. Break gold pots for extra resources, and check the mini-map before leaving a room for hidden chests. These often contain Charms, loot, or extra gold.
8. Build Flow and Aspect Choices
Early in a run, diversify your upgrades across your primary, secondary, and ability slots for balanced coverage. Once you reach the third or sixth selection, start committing to a single element to unlock stronger Minor or Major Blessings. Offensive Aspects such as tentacles, fire, or ice often provide the best early momentum, while defensive ones can be layered in depending on your playstyle.
Why Choose Co-Op in Abyssus Over Solo Runs
Playing Abyssus with friends doesn’t just make expeditions more fun—it also gives your team real advantages that solo runs can’t offer. Here are some of the biggest reasons why multiplayer is worth choosing:
- Shared Firepower – Clearing rooms is faster when four players unload their arsenals at once.
- Build Synergy – Teams can experiment with combinations of Charms, Aspects, and Blessings that wouldn’t shine in solo runs.
- Objective Management – Multiple players can split responsibilities, handling puzzles and combat simultaneously.
- Learning Curve – For newer players, co-op can make the game’s early difficulty spikes more manageable.
If you find co-op too punishing, consider a few solo runs first. Enemy health pools and spawns scale down for solo play, making it easier to unlock weapons, blessings, and upgrades before diving back into multiplayer.
