Occasionally (maybe 5% of the time? [Tie % to a cvar?]) a randomized event happens. Maybe a unique variant of Roboenza appears that changes how the game is played, or Eclipse attacks (since canonically this takes place during the MM10/V chapter "on the streets"), or it's a reverse boss mode where one player is The Chosen and has to fight everyone else who is infected.
Each event type should probably be its own CVar toggle.
