In addition to units found in this collection, an additional oversize unit called a Mega Model was available during April as a prize for one of the tournaments scheduled for that month. It is a reprint of a unit with the same name from the collection (with the same statistics and markings), but printed on a 1/4" styrene sheet. Though a third taller than a 12 fl. oz. (355 mL) aluminum can, the unit is considered competition legal and may be used in games and tournaments.
