Until recently, this was the most recent of my Robotech RPG acquisitions (well, before the Reboot that is - but we'll get into that later). It has been been out of print for a long time and as such was quite difficult to find. However, my earlier complaints regarding Invid Invasion and its lack of substance and story are answered by this supplement.
The setting of the adventure contained herein is primarily Southeast Asia; however, it does branch off into near Earth orbit and the Moon before returning. A group of Tirolians/Robotech Masters have managed to stay hidden from the Invid deep in the jungles of Southeast Asia and have made contact with a couple of Zentraedi groups also in hiding. I won't go too much in-depth, as it really is a very unique and interesting story which, if done right, could have very interesting long-term consequences.
There are some unique rules for the Mecha Su-Dai, a sort of kickboxing sport for Mecha and full-sized Zentraedi, some floor plans for REF bases on the Moon - which have heretofore remained untouched by the Invid and could be a new staging area for the players. There are also new Drone Mecha onboard a potential Factory Satellite as well as new Robotech Masters Mecha if they are tired of the same old foe. And if your players are getting tired of their Mecha or in need of some new ones, there's a small section of new and prototype Mecha they could pilot and use against the Invid...or others.
