The mission is to destroy all Mechanic units sneaking into the bases of all three species. The battle field is the unlimited outer space and you can enjoy the view of enemies falling into the endless depth after you have shot them down.

The monsters overall are rigid including SN-4. You would find the stage tougher than the 4th. Items and Gold are more loaded. You would find items of level v5 and even v6 if you are lucky and you will come upon 1000 Gold pretty often.

To get rid of the boss which teleports itself to various places you have to make up a full squadron. You will get an item of level v6 if you kill the boss.
