I initially thought about playing as an apex would be finding your “target” for a set amount of time (And it would be crowded, like 20 or 30 students).
If the developer wouldn’t want to code the entire AI that searches keys and unlock rooms, some of the students will be locked inside of rooms where you’ll have to find the keys to unlock it (And one of them contains the target that’ll blend in the students that makes them less suspicious, but they’ll still attempt to crouch and hide in obscure places).
The lore stated that one of the students knows too much, so the apex predator is tasked to eat them before they’ll escape and spread the news.
