OOOORRRRR you can edit the weapon_soulcube file
pak000.pk4\script\weapon_soulcube
You can open the PK4 just using winrar or other similar
Then find the number 5 or the maxammo or ammoclip ammosize clipsive or something like that. Then change it to 0 or 1. If you use 1, it signifies if you use the soulcube with anyone, (in exeption: Cyberdemon) it will come back to you loaded, but if you put 0 on the value, it signifies that, even fighiting the cyberdemon, you dont need kill nobody
Dude, i can't find the number 5 or the maxammo or ammoclip ammosize clipsive. i can't even find number 5!! please direct me to it!!!
