Co‑developed by Timelock Studio and Croteam, the standalone chapter adds new foes, bosses, and an expanded arsenal that includes the legendary AK and experimental Perun crossbow. It also offers a level editor with Steam Workshop support and supports single‑player, multiplayer, online co‑op and full controller use.
01 / THE GUIDE
Siberian Environments
The game features five new levels set in distinct Siberian locales, from Arctic coastlines to desolate forests, abandoned villages and a chilling ghost town. The description emphasizes that each area is huge, cold and unpredictable, encouraging players to move freely while staying alert to environmental hazards.
It also notes that the world is large enough for players to fight and explore for as long as they wish, and that surroundings can convey unexpected information. This suggests that visual cues and ambient details may provide hints about hidden paths or story elements.
- Observe distant landmarks; they often indicate the direction of the next objective.
- Pay attention to environmental sounds, as they sometimes signal hidden encounters.

New Enemies & Bosses
Siberian Mayhem introduces a fresh set of dangerous foes and bosses that join Mental's Horde. The description calls these creatures some of the most advanced and intimidating creatures you never expected to see, expanding the combat challenge beyond familiar enemies.
While specific attack patterns are not listed, the presence of new bosses implies varied behaviors that require players to adapt their shooting tactics and positioning within the expansive Siberian arenas.
- Watch the first attacks of a new enemy to identify safe windows.
- When facing a boss, keep moving to avoid predictable damage zones.
03 / THE GUIDE
Expanded Arsenal
The game adds new weapons such as the legendary AK and the experimental Perun crossbow. These are highlighted as part of a “deadly arsenal” that lets players choose between rapid fire and precise, long‑range attacks.
In addition to weapons, the description mentions new gadgets and vehicles that are “locked, loaded, and ready,” indicating that players will have access to additional tools for destructive strategies beyond standard firearms.
- Try the Perun crossbow for enemies at a distance where bullet spread is less effective.
- Switch between the AK and heavier weapons to manage ammo consumption during long fights.

Co‑op Multiplayer
Feature tags list single‑player, multiplayer, co‑op and online co‑op, confirming that the game can be played alone or with others, including online co-op over the internet. This allows friends to join Sam on his Siberian trek and share combat duties.
Because the levels are described as large and open, co‑op play can involve multiple players navigating the same environments together, coordinating attacks against the new enemy roster.
- Coordinate weapon choices with teammates to cover both close and long ranges.
- Use voice chat or quick messages to call out enemy spawns during hectic waves.
05 / THE GUIDE
Level Editor & Steam Workshop
Siberian Mayhem includes a level editor, enabling players to craft their own maps. The description states that this tool is paired with Steam Workshop support, allowing creators to share their maps with the community.
Community‑created maps can introduce fresh challenges or entirely new settings, extending replayability beyond the built‑in campaign while staying within the Siberian aesthetic.
- Start with the provided templates to learn basic placement and lighting.
- Browse the Workshop for popular maps to see which design choices resonate with players.
