First copy the folders inside "copy into ut2004" into your ut2004 folder, then copy the rest 
of the .U files into the system folder in your ut2004 folder.(The ones not in the "copy into ut2004"  
folder, these are my modded gun versions).

Wayne's Guns How To: (turn word wrap off for ease of weapon name finding)

Type ''summon'' then the guns name. eg. ''summon trencher.trencherpickup''
except the '' s. 
The guns are as follows:

trencher.trencherpickup  -  link gun sniper rifle, unrivalled range, unrivalled R.O.F., very Very nice damage ... really awesome gun. teammate safe even with friendly fire. most of the time.
trencher.trenchcannonpickup  -  flacannon mod with faster primary fire and a secondary fire that on some terrains dig holes!!!
(flakammo should work for the trenchcannon)  Should.
mymini.myminipickup  -  minigun mod... excellent anti personell gun with great accuracy, medium range.
gsr.gsrpickup  -  sniper mod that fires .100 bullets, takes a little getting used to, faster R.O.F. to compensate... you'll see.
insta.zoominpickup  -  lightning gun mod that shoots like a insta gib... but just a very very little bit faster than the original. a must try.
omfg.omfgpickup  -  rocketlauncher mod alt is still rockets but a little different, primary fire is large .100 (100 calibur) rounds that kill almost anything in one hit.

(note: the mods required to use most of these guns are as follows, without them i dont think they will work.
remote_strike, omfg, erl(enhanced rocket launcher), flakrifle and unreal tournament 2004... 
or mabey not the last one...Lol. these are the package file names (aka the .u files)

To change the crosshairs and other things with the weapons that arent in the weapon config menu
just start a game up, summon the selected weapon (eg. trencher.trencherpickup) pick it up, but make sure
you dont have the original weapon (eg. the link gun - trencherpickup, drop the link gun,the really good guns you cant drop.)
then go to the options menu, weapons config, select the original weapon (eg. the link gun) change what you like. start a new game, 
pickup the original weapon,go to the options menu, weapons, and change it either back or to something else, not nessecary but it makes the guns different, 
even classic looks work.

superhealth.superduperhealth  -  health with a difference, made for invasion rpg.
superhealth.ssp  -  supershield pack 1X = 150
SUPERHEALTH.UNLIMITEDDAMAGE  -  double damage, well i tried, and failed, but i did the next best thing. count them.. 99999 seconds till it runs out, 30 seconds to respawn. 

Now the vehicles:
same procedure as above except you MUST HAVE GOD MODE ON. otherwise the vehicle squishes you.

mst.onsmstank - mod of the paladin, excellent shield defence, excellent power, unrivalled offroad ability, rapid fire cannon...mmm deadly?
mst.mytank - mod of the ion plasma tank, instant fire, rate of fire increased, not so good offroad, but more power than normal tanks.

(note: all youll need for these vehicles to work is ''onslaughtbp'' the editors choice bonus pack. again the .u file). and just incase you dont 
have it installed UT 2004 might b required.

Hope you enjoy it.
ps. im sorry for any copywrite infringments, i was just having fun.
