It reminds me of a big swathe of survival and/or base building games where you have to balance out things just right, or real life games like Werewolves.

Now I'm imagining a variant of Werewolf where only a handful of the players even know how many werewolves there were at the start, possibly zero, and there are also non-werewolf causes of death.

Will the villagers wipe themselves out in a witch-hunt?

May i ask what genre?

Doesn't have a name, but a mix of battle royale, among us, and Oregon trail.

If I had to call it something, perhaps...

Civil Royale

Treaty Jam

Governot

Pavillion Shorts

Rotator Commandant

I dunno, something to that effect.

It's closest to a "hidden role" game, like werewolf or Town of Salem.

There's a general task that everyone (often even called a "crew" in space based flavors) has to complete to win, but there are people who are essentially secret saboteurs who are trying to complete a different objective that often explicitly causes the rest of the players to lose.

Look up Secret Hitler, which explicitly has you voting for government leader, different factions, and voting for which actions to take as a government. Your goal as the crew is to vote for democracy or uncover hitler, and your goal as hitler or a facist is to do facism.
