Yeah. Still, that's probably not been the reason why it was dropped. After all, it was mechs like the Phoenix Hawk and Wasp that got dropped because of the lawsuit with the creator of Macross. The marauder probably got dropped because of the success of the Timberwolf/Madcat.
Still, if you get the MekTek Mekpaks, the Marauder makes its triumphant return, along with its cooler cousin, the Marauder 2.
