This is a fun mission type to play. Players play as individuals. When the mission begins, a number of players are selected at random and become "IT". The more players there are in the mission, the more players there are who will become "IT".
Their goal is to "tag" some other player and thus make them "IT". They do this by missiling them. Only players who are not already "IT" can be "tagged". The goal of the other players is to score points by zapping the tagged player(s) while avoiding being tagged themselves. Once a player is tagged, they are deactivated for four seconds, and then are reactivated. The player who tagged them returns to normal mode.
Notes: While tagged, a player cannot fire normal shots, just missiles. They cannot score in any way and must simply try to tag another player by missiling them.
While tagged, a player is never deactivated. They remain up the entire time, and will likely have all other players zapping them repeatedly (from a safe distance). The tagged player loses points each time they are zapped, so they should try to tag someone else as soon as possible.
If a player remains "IT" for too long, the computer will take pity on them and automatically "tag" someone else at random for them. Becoming "untagged" in this manner incurs a substantial points penalty.
