Get free banshees on the Packaage
This trick needs 2 players. First clear the first 2 areas, and try to grab a ghost as well. its not absolutely necessary but itll make it easier. at the southern end (the direction you're supposed to head) theres the shack where you previously had to turn on the generator. On the northern side of this shack, right on the ground, theres a crate sitting against the wall. Usse the ghost or melees to move the crate. one player should stand where the crate was and face the wall. The other player should continue south and grab the scorpion, just to quickly clear the second area. Head to the water at the far left, where theres a pile of rocks. Walk of the rocks into the water and immediately go left. Youll see a green panel, you have to activate this and then get back into the playing area quickly if you dont feel up to dying. As soon as you hit your sswitch, your partner the crate whisperer should see another switch appear in front of him, this he has to hit quickly because it will vanish soon. As soon as the button is hit, four banshees will appear on the roof of the northernmost building. You can now explore the entire level, even the dogfight to the south. If you take out the enemy AA before you get the banshee buttons, youll even be able to fly through sword base's entrance gate and explore even more of the level. You cant destroy the guns afte3r you get the banshees, they become invincible when you hit the switch, so make sure theyre already well past dead.
