Heli Attack 2/Glitches


 * If you take an atomic bomb launcher and fire it at the overhang, (while you are underneath it) you should explode and go underground. The only known way to come out of the ground is to hyper jump. It is impossible to be hit with enemy fire when underground.


 * Similar but very rare: If you kill a heli while on a hyper jump with an A-Bomb and land you will go underground and only be able to shoot with the RailGun, grapple cannon, rocket launcher, RPG, and grenade launcher (note that these are the only ones known, there are likely others). While underground the helis can still hit you. To get out move around and jump/hyperjump in the right place.


 * If you go all the way to the end of the level, and stand under the overhang, there is a glitch where you can never get hit. What you do is you stand under the overhang, but don't touch the wall on the left hand side. Next hold the left button down, and just as the soldier touches the wall, hold down the "down" key. Keep the down key pressed in order to remain crouching, this will make you un-hittable. From there, you can fire the Rail gun, the Grapple Cannon, the A Bomb launcher, Shotgun Rockets, and Grenades. You can also shoot the Seeker Launcher if you shoot it at an angle. to get out, simply press down (to do go on top of the overhang) or press left to go below the overhang. You can also hyperjump out of there.


 * Occasionally when a heli flies off and returns, it will be entered in the tally at the top of the screen as having been killed. However, you will get no points for this "kill." It is unknown whether this affects when you get the next Health Pack.


 * If you get the bonus pack "Invulnerable", you cannot use health packs even though they are dropped from helis, no matter how many helis you kill.


 * In Internet Explorer, click and hold the left mouse button down and drag off the game screen (and then let go of the mouse button). If done correctly the 'gun' you have will continually shoot without the need to hold down the mouse button. If the mouse button is re-clicked the gun will stop shooting.


 * If you get a kill that results in a weapon crate being dropped on the top-right of the map, the crate will sometimes become lodged in an invisible crevice. You can reach this crevice by hyperjumping, however.


 * You can get a score of -1 which is counted as the highest score in the high score list, though it is not known how to do this.
