The Federation has issued a CRITICAL RED ALERT to Moon Base Command to prepare for a massive asteroid assault. You as the base commander must operate the protection system and take control of the missiles and two Plasma cannons. Each Plasma cannon has a limited firing capacity, a max range and an overheating protection system. The Federation has explained that it looks as if there will be [5] waves consisting of groups of asteroids heading towards the Moon base with four waves of asteroids per group. Each asteroid will be represented by a d6 die. You must protect the moon base and keep each of the three bases from being destroyed.
Victory conditions:
Your goal is to protect the Moon base at all costs. You must save at least 1 base with a shield value of at least one. A total victory would be all bases saved with full shield values of six each.
