@Zara_588 There were 40 people in the room, and you entered, making 41. The killer then kills 25 people, but the 25 dead people are still in the room, along with the survivors.
So the answer is 41 people, assuming nobody leaves the room.
@katsuxbt No one could stop Mahmoud Abdul rauf in the 90s. The only problem with that guy is he has no decent teammates compared to steph. But steph is way better than Mahmoud Abdul rauf
