When you are low on health, and your rival is tailing you, find a spot with a lot of space between floor and ceiling. Switch to Star Shell, and fire straight up. Bullets will rain down, creating a wall that your enemy cannot pass, even if he wanted to. Note: A disadvantage to this is that you also will not be able to pass.
Catherine Wheel
Try to stay above it. The small particles that the Wheel launches are still pulled by gravity.
Fly through walls
If you are stuck in a thin stone-walled "prison", such as in the Sokkelo level, walk to the wall, switch to the Vox. and shoot in the opposite direction from the wall. The recoil from the Vox will fire you through the wall.
Instant name
To get a pre-written name, such as Gaurgul, Lozzi, Onyx, etc., clear the "Name" field in the player 1 or player 2 options. A name will be filled in. If you want to add another pre-saved name, use a text editor to modify the "names.dat" in the game folder and type in the name in the list. Note: Make a backup of the file before proceeding.
Periscope effect with G Raider
If your enemy is around the corner, fire a G Raider so that it will hit the ceiling and bounce back into the enemy. Even if you miss slightly, the bombs that the G Raider launches will get him.

The following informaiton is for WeaponHack, an add-on to LieroKit, which is an add-onto Liero. : At the end of the list you will see "12 -Unknown," "13 - Unknown," and "14 - Unknown." The first unknown is explosions (Hellraider-style); the second unknown is smoke (missile-style) and the third is nothing (cluster bomb style).
WeaponHack: Most objects possible following projectile
To get a steady, constant stream of explosions, pixels, or smoke, pick your object trail, then go to page 3 and switch the "Type Of Shot" to "4 - Laser type". This will create an incredible stream on your object trail.
