This have to be done as an Imperial on SP.
Spawn at the sandcravler and jump on the swoop fast.
Get to the homestead and take the rebel tank.
Shot everything that moves and every rebel are after getting you.
Hopefully you can get to a r4 or be a pilot.
Just drive so you don't get hitted by the nades and you will be fine.
Now as every rebel are on you the Imperials got no problem getting to you and the homestead is under siege of the Imperials.
