* some of the enemies follow in calon mission especially these drainer mission with the methanoids-pirates enemie.
the next mission should be "House Calls" it tends to fail a lot. in this mission you have to destroy the pirates bunker, there are 4 or 6 if i remember correctly. in every ~5%-10% you shoot some enemies will arrive. prepare to kill every enemie and make sure when you destroy the last bunker that your systems are ready. clear the minefields and catch the pirate leader barossa. do this in squad its better but it is possible solo with outside cover. barossa is fast you could use magnet traps and stuns. every pilots needs to be in the same flight speed if one is far away it will fail and dont kill him , sar team will arrive and will capture barossa and mission is done.
