How many players can play Keep It Up! together?

How many people can play?

The advertised maximum is four players: you and up to three other Facility test subjects. Steam also lists single-player. A four-player maximum does not establish a special mechanic for each possible team size.

Is voice chat included?

The official description advertises in-game voice chat. Check the current build’s audio controls before the run. If your group uses a separate voice app, agree one set of short handoff calls so competing conversations do not cover the balloon call.

How can the team avoid talking over each other?

Try a balloon caller and a route caller. A third or fourth player can watch the next handoff or recover position. These are suggestions, not formal roles or a requirement to bring four people.

Show a simple handoff plan

Call who takes the next touch, wait for an acknowledgment, and move only when someone still has the balloon in view. Reassign the caller when the room changes.

Start with the first-run guide, revisit the balloon objective, or use the scene reference together. For installation, use the demo guide.
