Escort defense! Mantis and Human modes available.
This is quite different from your ordinary place-buildings-and-let-them-shoot classic. There are two modes, Mantis and Human.
Mantis mode:
Every player that has applied for the event (or is on the planet) has his map updated with a "path" - a crooked line going through tights spots, spots filled with non-event mantis etc. from one part of the map (top-left, etc) to the total opposite of the map (bottom-right, etc). The players have one minute to set up, that means placing 2-3 people on different parts of the map, or even whole squads to defend the crooked line! Once the game starts, a huge wave of the strongest enemies in the system is created. Vega could be (the way in which they appear, and all of them have the highest rank in the system):
-Custodian Commander
-Three Sentinels
-Mender (all menders from this event have their range increased +20% to cover all units)
-Two Avengers
-Custodian Commander
-Three Sentinels
-Mender
-Four Avengers
-Sentinel Commander
-Custodian Commander
-Five Sentinels
-Mender
-Six Avengers
-Mender (again)
-Three Marauders
-Marauder Commander
-Two Custodian Commanders
-Ten Sentinels
-Mender
-Ten Avengers
-Mender
-Ten Marauders
-Mender
-Ten Sentinels
-Mender
-Sentinel Commander
-Marauder Commander
And the last part, of course:
-Custodian Commander
-Custodian Commander (one after another, not like paired)
-Ten Marauders
-Mender
-Behemoth! (this one has twice the health AND twice the firepower of the ordinary one)
-Mender
-Ten Marauders
-Sentinel Commander
-Marauder Commander
The point in this event is to not let the enemy escort reach the last part of the map, where there is a huge patrol of the next system - highest mantis there (so if you're on Vega, the patrol on the end of the path would be like five rank 25 Custodians, twenty rank 25 Frenzoids etc. just enough so you get obliterated).
Only tech from that system is allowed, the game should be programmed so you can't land if you have anything more than e.g. Vega tech (rares are allowed!), not just let the GMs try and check every player.
Once the escort (with the Behemoths etc) is defeated, random cryonite is spawned all over the map. This should be a formula:
h = highest cryonite available in the system (so in Vega, like 50-60 because of the Harvies)
h x 2 + (h/2) for each cryonite. Moon events would get you rich faster than you can say "STAM-R Armour, here I come!"
Hope this sounds like a good idea

P.S. I'd like to see what you guys think of what the Human mode will be =) I'll try something unexpected, if I can make up something
