Why? Have you never had alliances in your Mafia games, like "we won't kill you for two turns, and you help us take down that guy over there"?
Of course, there was that in the Winner game. Someone told Ment, "You eliminate Asajj, and we won't hang you right away." :D Isn't that an alliance?
There are 4 teams and 2 neutrals.
Just like here, each role has its own characteristics (called "passives" and marked with *) and a set of stats (personal and team (racial)), which are not marked in any way. The difference is the health reserve (HP). When attacking, the player does not die immediately; a certain amount of HP is deducted from them, depending on the attacker's stats. When HP reaches zero, the player is sent to the grave.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
