Monobeast

Hospitals may find themselves infested by vermin! The Monobeast detaches from a patient when successfully cured of Monobrow, upon which it will move independently throughout the hospital. After a breakneck escape and brief explorative foray, monobeasts will take it upon themselves to take refuge underneath vending machines, bins and various other items, and will not come out until the item is either picked up or sold. They will not enter rooms, only remaining in corridors. Although they do not cause any negative effects, it is possible to rid the hospital of them.

There are two main ways to remove monobeasts from the hospital; one is to use the Browbeater item, detailed below. The other is a more involved process: when there is at least one janitor in the hospital, the monobeasts become the target of a shooting game. When the player mouses over a monobeast, the cursor will become a targeting reticule. Clicking the left button will fire on the creature, and if a successful hit is achieved, the monobeasts will meet a messy death. The remains, which are highly unhygienic, will then be left for a janitor to sweep up. It is important to note that the targeting reticule will not available if the game is paused or on slow speed.

There are two Steam Achievements related to the monobeasts shooting minigame:

Browbeater
The Browbeater can be obtained by completing Hair Removal, the first local project of The Superbug Initiative. When placed in a hospital, it will attract and contain monobeasts. Aside from the corridor, it can be placed in the GP's Office, Ward, and Café (to maintain hygiene). When they are separated from their Monobrow-afflicted hosts, the monobeasts will, rather than hiding under their usual items, find their way to the Browbeater and work their way inside.

It should be noted that once a monobrow is in the Browbeater, it cannot be freed by removing the item; instead, the monobeast will be removed with it. As such, it is not advisable to use the Browbeater if the player intends to complete monobeast-shooting staff requests. This item will also make it impossible to complete certain level challenges.

Trivia

 * Shooting monobeasts is a reference to Two-Point Hospital's spiritual predecessor, Theme Hospital]. In Theme Hospital, the player could shoot rats that infested your hospital when hygiene became too low. The game even included dedicated bonus levels purely for shooting rats.
