Your helicopter will keep going across the screen left to right...just press X to drop the bombs. Every time the heli reenters it moves down a space, so be sure to take out those tall buildings first...or you'll crash for sure. The High Score version takes you to another site online, so don't click that if you want to play offline. However I highly recommend you check out http://psp.fingertime.com for three great PSP games that work beautifully on the browser...unfortunately this is the only one I can make available offline. You'll have to go online with your PSP to check out the other two (Sudoku and a cool Kong game). Source: PSP-News
