Use
There are several mutators available:
If you need more flexible control of weapon replacement, I suggest you try one of the many excellent mutators already available for the purpose (e.g. SwitchArsenal).
Note that UT2004 will usually automatically give a lower priority to WoE weapons than the standard weapons. You may therefore find that you automatically switch to the Shield Gun instead of the Soar. You can fix this simply by assigning appropriate priorities to each weapon in the settings menu.
If you run a server with any of the mutators, you must add the packages to the server packages list in UT2004.ini. Add the following lines under the section labelled [Engine.GameEngine]. Make sure there are no spaces at the end of the lines:
ServerPackages=WoE_Effects
ServerPackages=WoE_Weapons
ServerPackages=WoE_Sentinel
ServerPackages=WoE_Inventory
Note, If you don't use the Sentinel you don't need to add the Sentinel package, and if you don't use the inventory you don't need the inventory package, but the effects and weapon packages are always needed.
