MSC Infection

One player starts infected. Every survivor they catch joins the infected team. Be the last survivor to win.

Set up a match

Open MSC Infection from Throwdowns or Insert. Choose 2–10 players, a 30–600 second match, and the chaser speed boost before placing your flag.

The boost defaults to 15%, with 0–100% available. 0% turns it off. Every infected player receives the same boost to pushing and on-foot sprint speed. Survivors keep their normal movement. The setting stays fixed for the match. A message appears if the session's movement rules block the boost.

Press X / Square to place the flag. B / Backspace cancels placement. Other players join with X / Square within four metres. The top-left card shows the joined players and host. At least two players must join before the host starts through the lobby menu or X / Square at their flag.

Play

After the countdown, patient zero begins the chase. An infected player converts a survivor by getting within 60 cm of their body. Physical collision is not required. Conversions are permanent for the round.

A newly infected player bails. On a board they also receive a small knockback; on foot they bail without an extra shove. Already-bailed players are not knocked over again. New infected players have a two-second incubation period before they can convert anyone else.

The HUD shows survivors, infected players and time remaining. The last survivor wins. If all remaining players are infected, the infected team wins. When time runs out, remaining survivors share survival; a shared result has no single winner's payment. Cancelling or abandoning a round does not award a payment.

During play, Start / Options opens the match menu. Resume, leave, or use the host's option to end the match for everyone. Insert also opens the menu.
