Especially the non-booted one I remember with dread and I did complete both but I found them unpleasing experiences. I spent some time thinking about this level, for example the reasons why would anyone put immortal Bartenders in their level and so. Once I returned to replay the level with the stealth-puzzle mindset, I think it 'clicked'. Playing the level as an open-ended "clear all enemies" was the wrong move.

The sniping part has no stakes whatsoever, so it felt vapid to me. I liked the look of the level there though and wished I could have actually played in it.

That trap on the elevator door is pretty high on the bs scale. It's easy enough to disable when you come out of the elevator. Most of the time the enemies seemed to trigger it. What bothers me is that even after know about it, I have a really hard time seeing the darn thing.

This is a good level I think, but I find it an extremely obscure choice to have it as the first level of a collection.
