Here’s what I would have done to Bangkok, and whilst not a drastic change, it would have added a slightly better immersive hotel, and another opportunity to kill your targets.
I’d add elevators, but, and this is the big one, they wouldn’t be working.
I understand that elevators was a mechanic that IO couldn’t add in, so you put them there, but they’re out of order.
One on each side of the lobby leading to both both floors. A couple of workmen have some dialogue about how taking all that heavy equipment upstairs broke them and what do you know, they’re both on the same ccircuit breaker which is why both are broken and not just the one.
The only elevator doors you can open are the ones on the top floors, and to do so you can use a crowbar, maybe dressed as an engineer to avoid suspicion. You can lure Morgan and Cross in different ways and push them down.
Challenge - ‘Getting the shaft’.
So yeah, a new way to kill your targets but elevators added to make it a more realistic hotel, plus a reason why they cannot be used, avoiding the need to ty and add a fiddly elevator mechanic. Essentially all you’re adding are 2 long holes and calling them elevator shafts.
