About C.U.B.E
C.U.B.E is an online co‑op horror experience for 1‑6 players where groups endure ten days of deadly Trials. Each day presents a new, randomized challenge that tests puzzle‑solving, survival, and adaptability. While teamwork is essential, players also vie to keep their personal death count lower than the others.
At the end of Day 10 a single player is crowned the True Subject, triggering the Final Evaluation where the remaining participants get one last chance to claim the title. The game offers a large pool of unique Trials, cosmetics, voice chat, and both single‑player and multiplayer modes.
01 / THE GUIDE
Gameplay Overview
C.U.B.E supports solo play but shines in online co‑op for up to six participants. Players must survive ten consecutive days, each called a Trial, which are randomly selected from a pool of 25 unique scenarios. The core loop mixes puzzle solving, navigation, and survival against the facility’s experiments.
Death counts are tracked per player, and at the end of Day 10 one player is chosen as the True Subject, with everyone competing to keep their death count lower than the others. The game includes proximity voice chat, allowing players to coordinate in real time while the facility throws unpredictable obstacles.
- Communicate early about each player’s death count to plan riskier actions.
- Observe how the random Trial selection changes pacing and adjust your strategy each day.

Trials Variety
The trial pool currently contains 25 distinct challenges, each introducing a different type of puzzle, experiment, or hazardous environment. No two days are ever the same, providing high replayability as the order of Trials is randomized each run. New trials are planned for future updates.
Each Trial forces players to adapt quickly, using a huge variety of discoverable items to overcome obstacles. The randomness ensures that players cannot rely on memorized solutions, keeping each session fresh.
- Take note of items you discover early; they may become crucial in later, unknown Trials.
- Experiment with different approaches in each Trial to find the most efficient solution.

Competitive Death Count
While survival depends on teamwork, the game tracks each player’s individual deaths. After ten days, one player is chosen as the True Subject, and everyone competes to keep their death count lower than the others, adding a subtle competitive layer to the cooperative experience. This mechanic encourages careful play alongside group coordination.
Players can monitor their own and others’ death counts throughout the run, influencing decisions such as who takes risky actions or who stays back to support the group.
- Balance risk: let higher‑death players handle the most dangerous tasks.
- Use voice chat to call out when a teammate’s death count is approaching the lead.
04 / THE GUIDE
Final Evaluation
After the ten‑day run, one player is chosen as the True Subject, triggering the Final Evaluation. This stage gives the remaining participants one final opportunity to contest the title, adding a climactic showdown after the main Trials.
The Final Evaluation is separate from the regular Trials and serves as a concluding test of skill and strategy, wrapping up the ten‑day experience with a decisive moment.
- Prepare for the Final Evaluation by conserving useful items during earlier Trials.
- Discuss potential strategies with teammates before the evaluation begins.

Cosmetics & Voice Chat
C.U.B.E includes character cosmetics and unlockables, allowing players to personalize their appearance. These cosmetics add a layer of expression during co‑op sessions. Proximity voice chat is built in, facilitating real‑time communication among nearby players.
Both cosmetics and voice chat enhance the social aspect of the game, especially in public lobbies where strangers can coordinate or showcase their unlocked outfits while navigating the Trials.
- Use voice chat to quickly alert teammates of imminent hazards.
- Experiment with different cosmetics to identify which visual cues are most noticeable in chaotic moments.
