Using strange palettes
If you have Wormhole and LieroKit v1.5, both downloadable from the Liero Hellhole, you can use several different palettes from the ones you can download. Open LieroKit, go to your Liero directory, and there should be a directory named "Palettes." Enter it, and there should be some palettes that can be activated inside. These palettes do not include all of the colors, so they will make Liero look strange when activated.
WeaponHack: Leave object trail Unknowns
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.
