Some pigs are pesky. It's very hard to kill all pigs in one shot without upgrades or power-ups.
Target score is very high.

Send a rebel bird north around the first planet. Split so that one bird will push the TIE Fighter into the gravitational field. Between the split birds and the explosion, all pigs can be cleared but it's easier said than done, there are some pesky pigs in this level.
