Sacrifice a friend

You and your mates find yourselves at a building where you see a shining altar. Someone has to go there. Not for uniting their legacies, but for losing one of their few lives. Help other players get there, by giving them a friendly push. Oh, and you can also pick up shit lying around and throw at them to stun them.
