"This is Commander Ryno of the 85th Battalion. Our transport came under attack above Tattooine. My squad and I were the only ones to escape. We took a pod down and crash landed near Mos Espa. While walking, we stumbled upon an underground bunker. It appeared that it was a Seppie one. Your mission is to find it and destroy it. Our worst fear, it may not be just a bunker..."
Okay time to get building. Make sure it is at least 12x12. One more thing: The part about the "worst fear", that is for you to decide.
Any questions about this mission may be asked in this thread.
