I guess I never thought of those. But yeah some of those would be possible but not all of them. "indigenous lifeforms invading colony settlements" that is happening all the time. 'Invading Earth'. I could see the weapons cache working as well as evacuation procedures.

Suspend rationality for a moment. Imagine a  Thorn Beast going rampant on a colony world. It's possible for an MMO, and entire plausible. While it may be happening "all the time," it would be perfect for a small side quest.
