Crossover - Mansion of Evil

- Geez, Max, turns out maybe you shouldn’t have killed so many people in your inane yet hilarious shenanigans. Now they’ve all come back to seek revenge on us! It’ll take at least the afternoon or a solid 3 hours of gameplay to get rid of this threat.
- No sweat, dear colleague, I got it all covered! Who do you think perpetrated the ritual?
- Yeah, come to think of it, it was silly of me to think you had not been involved. But why, though?
- See that undead over there? The one with a blue hoodie and half the face missing? You’re excused if you didn’t recognize him at first. Jeff from the post office, remember? The one I killed over the yoghurt? Well, I just came up with a way funnier way to kill him, and it just so happens to involve a zombie apocalypse! It was just too tempting! Meet me at 5 at the White House, will ya?

The real question is, are they allowed to actually kill the zombies or would they just bullshit themselves through the game via point and click mechanics?
