Might be quite usefull .. takes some getting used to but seems to work well
Your weapons are all numbered by default. To pipeswitch just open your "UT2004" folder..then open "System" folder..there you will find "user.ini" Open the user.ini with notepad and scroll untill you find the key you wish to bind to.
A pipeswitch bind will look like this" Enter=pipedSwitchWeapon 9 | pipedSwitchWeapon 4' This binds my "enter" key to lightning gun and shock rifle.
0 = Super Weapons
1 = Shield Gun
2 = Assault Riffle
3 = Bio Rifle
4 = Shock Rifle
5 = Link Gun
6 = MiniGun
7 = Flak Cannon
8 = Rocket Launcher
9 = Lightning Rifle
this makes switching between guns alot faster and easier.
