A much more complex version of the Shotgun, CrossGun is theoretically the best chip that is already in your ChipFolder. Like the Shotgun, it does 30 damage to its intended target. However, the CrossGun can also strike anything diagonally adjacent to the target, thus making its Total Attack Power a staggering 150 damage (generally 90, as there are only three enemies onscreen at any given time). This, in combination with Shotgun, Spreader, and M-Cannon will form the Program AdvancePowered Cannon?.
Like Shotgun, CrossGun hits more than just its intended target. In this case, it will hit anything diagonally connected to the target (thus making a cross or X). Everything that is hit will take 30 damage.
