I like the mission! This may sound nitpicky, but I notice you consistently use "Havok" instead of "Havoc", or rather, "Havoc Brothers". I think it is important, especially in this case where the missions are seen as applications, to adhere to OPRs naming standards. Same goes for "Daemons" instead of "Wormhole Daemons" - when writing about specific armies, you should use the correct nomenclature.
As said, this is is a minor nitpick but would save some Editor time in correcting you in the future. The mission itself looks fun and engaging, I think I might try it in the future!
