I think i seen someone saying they did co-op campaign and now i wanna!
Can you do it?
Could someone make a mod that allowed you to?
Do you think that cortex will ever have that?

In most of the scenes you can add to its activity file.

Cortex Command\Missions.rte\Mission Activities.ini and place it like


and it should add a second non-brain character of some sort. Doesn't work with some scenes, because of Lua dependencies I think, I dunno hopefully someone can elaborate.

But I'm pretty sure you can just add another character into those scenes and set the player count to 2. It should work. Most of the time they're landing in a craft, and all of the other times there's more than one actor anyway, so you can just add another actor into the craft.

That's not how it works. You have to manually assign a brain to a player. If you only spawn an additional brain, it won't have any effect on the second player.

The vanilla missions are designed to work with multiple players by checking the PlayerCount, spawning additional brains if needed, and then assigning the brainss to players.

The mission script ALSO needs to keep track of which brain "belongs" to which player, and to keep players from doing anything if their brain died.
