Begin game play on level 1 under the easy difficulty setting. When you approach the first Merc HAWC, move backwards and eject. Then use your GASHR to eject the pilot, get inside the HAWC and crush him. Destroy the next HAWC to win the level.
You must have a vehicle that holds passengers for this trick. First, go to controls, switch the eject passenger control on the 2 3 4 boxes to "D", and save it on all modes Start any type of game and get a passenger. When you press D, you will have unlimited passengers, but the passenger has to be in a different vehicle. For example, if you are driving the Scorp Tank and do the trick, you make your passenger in a guard tower, and he will stay there. If they are not in a vehicle, they will disappear. If you press D again when one of the passengers die (are ejected), then all the extra people will be killed.
