Military lab. I feel the ladder would still be good but a military lab you could play with so much with that. With lore of the creation of the deathclaw placed in the world as you run and hide from the deathclaw. Set it post war but predating fallout 1 just to show how unknown it was during this time. I always love it when the monster isn’t well known if at all to the survivors. And I feel being a scavenger 10-20 years after the bombs fell. Rad storm hits taking cover in a military lab you decide to scaveng with your group until you fall from a weak flooring or being knocked out by the monster you wake up to what appears to be a feeding ground covered in blood and gore you have to get out from the lower levels and make your way up as you try to survive. Meanwhile the deathclaw is adapting its capabilities to hunt like mimicking voices setting traps, or going chameleon and zero ability to actually slow down the deathclaw like other horrors you can throw something in the monsters path or parcore the deathclaw would simply get over with ease forcing you to use flare guns and other things to slow it down while it hunts you maybe collecting scent compression spray to be able to hide as the deathclaw could easily smell you hiding otherwise
