Gandos Unlimited Party

(Virtually) Removes the Party Size limitation, lets you open 12 player Lobbies and gives you the ability to recruit henchmen early in the game by the time you first travel to the end of time.

Bring all your friends for a big coop romp! :-)

You need to start a new savegame in order for this to work.
There is no way to bring mods to a existing savegame that I know of (if you know a way, please let me know ;-) ).

This will of course break the whole balancing and can make the game really easy. I recommend to play in tactician mode and without the lone wolf talent if you still want it to be of some challenge.
You could also split in groups to pursue different quest lines.

Its largely untested as of now.

The most bugs I encountered in test Sessions so far are GUI related.

Known problems:
-In Mouse/Keyboard mode a maximum of 10 party members can be managed in the character assign menu, more characters will be cut off in this menu.
-In Gamepad mode, all party members can be managed, but only the first 6 are shown, and the others are visually cut off, so you have to assign them blindly.
-In Gamepad mode, a player can only switch between the first 4 members of his group, as the GUI is not designed to include more than 4 characters. So remember to give a max amount of 4 characters to a gamepad player.
-In Gamepad mode, a henchman is not able to sell items to a NPC, as the selling menu does not show up.
-The character portraits in the sidebar can be cut off due to the UI scaling. You can still switch between characters by using hotkeys.
-The players who dont play as the source hunters cant listen to dialogue directly. They have to do it in the dialogue log.

To properly play in multiplayer with more than 2 players, the host needs to follow this guide, to disable the "Each player must have a main character assigned" Error message loop:

Have fun, and let me know of any bugs you may encounter!
