Neon-colored shirts or jerseys.
The xenomorphs must try to turn everyone else into xenomorphs.
Play in a large, dark building with all lights turned off, or outside in a clear area at night. Choose one player to be the first “xenomorph”. This player determines the area for the “hive” to be located. Give all other players (humans) a neon vest or jersey. Set a timer to two minutes and thirty seconds and say “Go!” The xenomorph must tag humans and escort them to the hive, where the caught player discards their jersey and lays down. After the time is up, the first xenomorph returns to the hive and sits. The victims stand up and are now xenomorphs. Play until everyone is a xenomorph.
