Causing mass pain
Abduct a person with the Abducto Beam. Just after you select store, release L1. They will slam into the saucer causing a huge bang.
Cop V Soldier
First get your awearness meter to yellow so cops and soldiers are searching for you. Next get the both of them in the same place (you can do this by picking up a cop/ soldier using PK). Lastly target the cop/ soldier using L1 and press protect and the cop/ soldier will shoot each other.
Defeat Bongwater without using weapons
Just target something with L1. Move the target around the room until you target an explosive barrel. Pick it up with PK and throw it at Bongwater. He will die instantly and after the movie clip, grab the disintegrater ray datacore and kill any remaining KGB agents.
IMPORTANT NOTE: Allways keep running around the room whilst you get a barrel, or Bongwater will hit you and you will drop the barrel.
Defeating Coyote Bongwater
When the battle begins, you should only have two weapons, the Zap-O-Matic and Disclocater. Neither of these weapons will work effectively enough to kill both Bongwater and the KGB agents. However at the start of the level, towards the left far wall, there is a large container of Revelade. Around these containers are small barrels. These are explosive barrels. Once the battle begins, quickly use the Jetpack to go towards the left side of the room. Once there, try to take cover behind one of the Revelade containers. While hidden, use your PK ability on one of the explosive barrels. Once you have it levitating, either quickly swing it at the KGB agent's or Bongwater's feet, or press Triangle again to push it towards them. Either will work, as the explosion is enough to take out almost all the KGB agents. Only about two to three explosive barrels are required to take out Bongwater. Do not get too close to the barrel when it explodes, as it will drain your shields drastically or kill you.

Once you have it levitating, either quickly swing it at the KGB agent's or Bongwater's feet, or press Y again to push it towards them. Either will work, as the explosion is enough to take out almost all the KGB agents. Only about two to three explosive barrels are required to take out Bongwater. Do not get too close to the barrel when it explodes, as it will drain your shields drastically or kill you.
Walk in, but not so far that the KGB and Bongwater notice you. Use your PK ability to slam an explosive barrel directly on top of Bongwater. They will not react to your presence in the room unless you begin to attack them or walk too close to them. This will not kill all the KGB agents, but it will kill Bongwater before cutting away to a scene before the KGB can finish attacking you. Once the intermission sequence is over, you can take out the remaining KGB agents easily.
First, kill the KGB agents with your Zap-O-Matic while trying to avoid Bongwater. When your health is low, jetpack to the ceiling and hide from the enemies so your shield will regenerate. When all the KGB are gone, jump onto one of the Revelade containers. Bongwater will run to the base, but he cannot hit you. Then, zap him to death from your elevated position.
Defeating Mutants
Take out your Anal Probe and shoot it at the Mutant. The Mutant will turn back to a human. You do not have to kill the human. Just kill the purple mist that comes out of it. Do not let the purple mist touch anyone else. To kill the purple mist, you can use anything except the Anal Probe. The Disintergrator works the best.
Defeating the KGB Boss in Alibon
Avoid his first attack by staying in motion and hiding behind a pillar or a box. When he is finished, take out your Anal Probe an shoot him once. He should start to turn back to normal. If not, try again. When he is back to normal, zap the green gas in the air and finish him off with your Disintergrater Ray.
Defeating the Tanks
When you finish destroying the blimps, a lot of tanks will appear. If you are in Two Player mode, the player in the turret can shoot the tanks and the player that is flying can abduct hippies and drain power from the tanks.

Gene Blender
When you're in the saucer, you can pick up and STORE humans! Either when you're ready to get in the saucer or while you don't have the abducto ray activated, press x to use the Gene Blender. Tired of your Holobob always being deactivated by majestic, well, no more Holobob, now you can steal people's bodies! But you have to use free love when people see you so you don't get caught. If your alert is up too much you can snatch an authority's body, call in the all clear and your alert will go down.
NOTE: On the first level the Gene Blender only lets you snatch people's bodies faster. And the last part of the gene blender on the first level, it only lets you use a male KGB and the rest are a bunch of question marks.
