Nonion Rings - Complete mission in under 240 seconds. - 750 Plex.
If you look at your map, you can see three corridors leading from the bottom of the map to the top. A cruiser will spawn in the rightmost corridor first, then the middle one, then the last one. Each cruiser will have three rank 5 escorts. Once the escorts are destroyed, no more will spawn.
If you want the bonus, you should bring a ship that's capable of quickly destroying turrets and then moving to the next corridor. If there's more than one cruiser on the map at once, you're working too slowly.
The low number of manned ships to kill may pose a problem for builds that are heavily dependent on building up veterancy ranks.
