Alien in the Jungle

You crash-landed in the jungles of Vietnam after your ship hyper-jumped in critical condition from a recent space battle, stranded on an unknown world. Your objective is to assemble the necessary technology from the local inhabitants and return to your home world. You must avoid being discovered by the humans who are distracted fighting each other; you may support one side or another for your personal benefit, go solo and fight alone, or maybe don't fight at all; it's all up to you now.
