This works better for larger groups. (Semi-endurance game) The “Aliens” are out only with a “Kill Shot”.
A space ship just landed in the woods. It carries beings from another world. They were sent here to takeover the planet. They do this, not by killing all of the humans, but by hitting them with a special weapon that transforms the humans into aliens. The world must be defended.
Approximately 20% (1 in 5) of the group start out as the rest are “people”. The aliens go out and set up either a defense strategy (ambush) or a roving / random attack force. The people give the first team 3 to 5 minutes then go out to hunt them. If an alien gets hit he/she is OUT. If a person gets hit they become an Alien
Once all of either team is elimnated.
Get all members of the other side OUT.
Aliens are only taken out via a Headshot
