Liero Xtreme gives you the opportunity to Mod the game. This means you are able to add your own custom made weapons with Liero Xtreme's EASY scripting.

First you will need the "game script Compiler" which is located HERE. The game script compiler comes with all the Liero Xtreme weapons source code's and a program called "gc.exe" which you will be using to compile your Mod. 

Once unzipping it you will find a directory called "Base" inside the "gc.exe" directory. Base contains all the weapon scripts from Liero Xtreme, here you can edit and add your own weapons (You may wish to copy and paste the base folder and rename it). Simply open one of the .txt files with any text editor (notepad) and edit to your hearts content and you can also easily learn the structure of each weapon to help you make your own. 

Once you have edited and such click the Windows start menu, then run. Type in the box 'Command'. This will open up MS-DOS PROMPT which will be used to run the gc.exe file. Go to the directory by typing "cd c:\progra~1\lierox~1\gc" or to wherever you unzipped Game script compiler to. Then type 'gc.exe' which will bring up a example on how to compile. 

This is the usage: GC.EXE [Mod dir] [filename]. So type "GC.exe base2 script.lgs" base2 being the directory where all the weapons txt are held and script.lgs is what to save the Mod as (usually just use script.lgs). 

Now make a folder in your Liero Xtreme directory and name it whatever you wish your MOD to be named and copy past the script.lgs into that directory. All you have to do now is run LieroX.exe and click "Local Play" and from the Mod drop down list click the mod you made!.
