Installation

Just open the UMOD file and the UT setup program should start.
If this doesn't work, you may need to download the UMOD fix or re-install Unreal Tournament.

Configuration

To start an Arena Match just add Arena Match to the list of mutators used in the game.
Unlike most other Arena mutators Arena Match allows you to use the translocator. Use the Settings page of the Start Practice Session or Start Network Game window to disable the translocator.
   
To configure Arena Match use Mod -> Configure Arena Match.

• Weapon Class
  Enter the class name of the weapon you want or right-click to open a menu where you can choose any UT or Unreal weapon and any other weapon registered in an .int file.
• Selected Weapon
  Shows the name of the currently selected weapon.
• Place weapon on map
  Select whether the specified weapon should replace all weapon pickups on the map. If this is unchecked these weapons are just removed.
• Place ammo on map
  Select whether ammo for the specified weapon should replace all ammo pickups on the map. If this is checked while Place weapon on map is unchecked all weapons are replaced by ammo pickups. If both are unchecked neither the weapon nor ammo pickups remain in the game like in InstaGib DM.
• Remove other items
  If this is checked all health pickups, armors, invisibility pickups and damage amplifiers are removed.
• Unlimited ammo
  Set ammo amount to 999.
• Random Weapons
  Opens the Select Random Arena Weapon window:
  
  When the Activate random weapons checkbox is enabled the Arena Match mutator randomly chooses a weapon from the list at the start of each match.
  The configuration window remembers all weapons you entered in the Weapon Class text box. As long as you don't close the window, all of these weapons are available through the right-click menu and in the Random Weapons window. When the Activate random weapons checkbox is disabled you can use the random weapon list as storage space for the weapons you added manually. They will be saved to the Random Weapons list and loaded when you open the config window again.

You can simulate (almost) any other Arena mutator like Flak Arena or InstaGib DM or create your own Arena mutator:

• Unreal Stinger Arena
• Redeemer Arena
  (not really useful, but not as dangerous as Vortex Arena)
• Vortex Arena (Enhanced Items version)
  (needs Chaos UT and Enhanced Items, use at your own risk )
• Mercury Missile Launcher Arena
  (needs Rockets UT)

There are several mods which declare their weapons for the weapon priority window, although those weapons usually are not shown there. The weapons of these mods and mutators are displayed in the weapon selection menu.
Here is a list of packages and weapon class names for some mods which are not (yet) shown in that menu by default:

• Chaos UT Weapons (GOTY edition)

  (These weapons are available through the right-click menu when Chaos UT is installed and ChaosUTWeapons.int is in the System directory. This file should be in the zip archive together with the UMOD file for Arena Match.)
  Package: ChaosUT
  Classes:
  • Sword
  • Crossbow
  • ExplosiveCrossbow
  • PoisonCrossbow
  • Flak2 (Claw firing Flak ammo)
  • Flak2Proxy (Claw firing Proxy Mines)
  • Flak2Melee (Claw in melee mode)
  • ProxyArm (Proxy Mines)
  • Sniper2
  • Sniper_RPB
  • VortexArm (Gravity Vortex)
  • TurretLauncher
  
  

• Frag*Ball

  • FragBall.FBHammer (the Frag Hammer)
  
  

• Namu's InstaCombo 2

  • InstaCombo2.DualShockRifle (the Enhanced Shock Rifle with a big bad combo move)
  
  

• InstaDead

  • InstaDead.InstaDeadRifle (another InstaGib variation with combo moves; alt-fire only pushes people around)
  
  

Credits

I started this because I wanted to test weapons without making a mutator for them and without using the summon command, but now it became a pretty good mutator so I decided to release it to the public. Special thanks go to TechnoArcher for the random weapon idea.

Feel free to mail me if you have any suggestions or want me to add some weapons not listed here.

Have fun.
