Infection

Infection is one of the three party gamemodes. There are two teams: the survivors (red) and the infected (green). Two players are randomly chosen to be on the infected team at the start of the round. Anyone that joins the server after the round starts or dies gets converted to the infected team. All players on the infected team have increased speed and jump power, but are restricted to use of only their melee weapons and hand-thrown weapons. The goal of the survivor team is to avoid getting killed by the infected, and the infected's goal is to kill all survivors. If at least one survivor is alive, the survivors win. If everyone is infected, the infected win.

 * It is the only gamemode to be restricted to two team colors, namely red and green.
