After a near fatal run in with a Zombie Hulk at the bottom of the stairs in a basement(thoroughly noped out of), I thought to myself, “What if I could activate a grenade, (e)xamine the stairwell, and drop the grenade down there to roll out the red carpet? I would think that this would require Z-levels to be active, for various reasons. Yes, it would be very edge-case use, but if I were in a situation where I know the thing at the bottom is nope worthy, I would toss a couple frags down and wait to see if anything’s still moving.
I personally don’t know anything of the code, so if I’m out of line here, let me know.
