When You Touch Me: Rage Of Aquarius side-mission

Screensaver  -  Remain idle and the screen will turn black and white, like an old television show.

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.

Causing mass pain  -  Abduct a person with the Abducto Beam. Just after you select store, release L. They will slam into the saucer causing a huge bang.

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 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.

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 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 Pongsby  -  Before the fight, refill the Mind Flash gauge and load your Disintegrator gun's ammunition. As soon as the battle begins, hold Circle to activate Mind Flash. You will have a short amount of time where everything stops. Take out your Disintegrator and blast away at Pongsby.

Flying  -  Play in Two Player mode. Have two players get on dumpsters next to each other. Use PK on each other's dumpster and press Up. You can have the ultimate flying or on-foot flying.

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.

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.
