you need to get the rat cave and then put on the rat suit. click on the mouse where you
normally get the mobile phone. when you go up to the alien the top button flashes, press
it. then the middle one will light up. ou have to aim it at the alien then go up to them
straight after that and use the third button and beat them up!!

you CAN use the rat suit IF you have the rat cave. but it works better to use the water
gun (if you need the water gun, go to town square and buy it for $250) make sure its
filled with water (fill from the well, oasis, sink by pressing the drop when it's in ur
hands. also, make sure the water pressure is on or it won't squirt)go to the alien without
it seeing you. once its in your veiwfinder thingy, press the target button. press the
'squirt' button. hope that helped!! ;)

stick to the water blaster method for fighting aliens.....dont worry if like me you broke
your blaster by over filling it...you will get another l8r on in the game
