Heli Attack 3/Zone 2-2


 * Enemies: 10x Helis

Like Zone 2-1, use Hyper jump with grenades until you run out, and then Hyper jump with the machine gun to kill the remaining Helis. There are 10 helis this time so you will probably use the machine gun more.

There is another secret, free weapon in this zone: the GooGun. On a wooden bridge next to a floor that goes upwards diagonally near the far right of the stage, hold Space and press S to crouch through the bridge. Drop down and fire at the walls to the right, then go through to get the gun.
