We saw this on TMP and thought here's a cool way to add some minis to the old collection and make new friends.
All you have to do is paint up a 5 figure team or squad and you will receive the same in return!
To quote ThorLongus, the organiser of this event: "This could be a coherent, uniform squad of any race, or it can be a mixed mercenary type of unit. The bare minimum is 5 average humanoid sized 15mm minis. If you want to include some oversized (think ogryns / super mutants) that is up to you."
