There are rules I have set for these matches for balance, but you can ignore them if you want to;
~ Players have their BAR off
~ Rockets and direct use of grenades is not allowed unless the player is the Juggernaut.

Action Skill:
~ Axton can use his action skill
~ Maya cannot use her action skill on other players
~ Salvador can use his action skill
~ Zer0 can use his action skill to avoid combat and shoot
~ Gaige can use her action skill
~ Kreig cannot use his action skill but he can melee

Free For All

To create a Free For All game all you need to do is change the Allegiance of all the players to '00000000' (Barrel)
In Free For All players simply kill eachother and the last player alive scores a point.
The maximum count of points per match should be 5, but it's completely lenient.

Juggernaut

To create a Juggernaut game you need to set the Allegiance of player who is the Juggernaut to '00000000' Barrel but keep everyone else's the same.
Every time the Juggernaut changes replace their Allegiance with that of the other players (they should all have the same Allegiance if they aren't the Juggernaut)
The Juggernaut will equip certain items that will boost their survivability.
In Juggernaut one player tries to survive against all the other players, when the Juggernaut dies the player that killed them becomes the Juggernaut.
The Juggernaut usually is confined into one room in the centre of the other players.
Juggernaut's score is counted in how many rounds you survive as Juggernaut and how many Juggernaut kills you have. 10-15 rounds a match.

Team Vs. Team

To create a Team Vs. Team match you must enter a duel between the 1st player and the 2nd player. Copy the 1st player allegiance then set the 3rd player allegiance to that. Copy the 2nd player allegiance and then set 4th player allegiance to that. Then end the duel and set the 1st and 2nd player allegiances to what they were in the duel (which are now stored in the 3rd and 4th player allegiances)

These allegiances should also be used for Juggernaut so that characters with pets won't hurt themselves.

Teleporting

We will use the Teleport Script to place players into their stating positions each round:
1. Go to the locations you want your players to spawn at.
(Use Blink mod to get there faster)
2. Save the positions by changing the 'Save Slot Position'* in Cheat Engine and pressing '0' to save it
3. Press '.' to teleport to the positions and then 4, 5, or 6 to teleport the other players to you to you.
*Right click 'Save Slot Position' and click Set Hotkeys, set a hotkey to set the value to '4', it will also show you what the other hotkeys are for 1 through 3.


Maps & Locations

Some maps have postitions that work well with these forms of PvP, these are some that I think work well:

Key:
Xv1 = Juggernaut
1v1, 1v1v1, 1v1v1v1 = Free For All
2v2 = Team Vs. Team

Because steam is a plebian and has deleted mediafire links I will have to put it in the description of a youtube video promoting this gamemode. Once that is done I will upload that here.
