Is there a mod to let you use them? I've been using HDWeapons but i really want the enforcer in U1 with 227, I found a method to modify your paths with the botpack system files to put the UT99 content in 227 but the only way I can get the weapons is by summoning them through the console, and they use separate ammo

Changing what type of ammo a weapon uses is pretty simple.

Open UED load package like 'examplepackage.u' which is in your system folder then find the weapon you want to mod on the list like 'thegun' right-click it -> Default Properties... A popup should open titled Default 'thegun'.'examplepackage' properties. In it open 'Weapon' find 'Ammo Name' and change it to whatever ammo you want and thegun is going to use that ammo example: changing it to "Class'UnrealShare.StingerAmmo'" makes the gun use stinger ammo. Ammo classes are found under "Inventory->Pickup->Ammo"

Check package name in the bottom of Actor Classes browser and save selected packages Voila.

Also, UTWeapons.u can be found on http://www.hypercoop.tk/frameset.htm Files->Mods under .:..:'s mods along with other UT stuff.

Edit: Forgot, if you want to use them without summoning then you need a mutator to replace the default U weapons which I can't help with much I'm afraid or edit the map and physically put it in there. Hope it helped.

I tested UTWeapons.u once and pulseGun have broken animations and these weapons do not make decals. Maybe that 227botpack is better. . Hmmm
