Started my version 1.1 playthrough on UV as opposed to HMP, which I used for my first time through. I'm loving the additional challenge! There have been quite a few times so far where I've been starved of ammo and health, which certainly isn't a bad thing if done right. Sigil, in my opinion, does this well. Being forced to play carefully and planning out my actions ahead of time is an enjoyable experience. I've also been using the MIDI soundtrack this time, which I'm very fond of. Buckethead's music is great, don't get me wrong, but the MIDIs definitely feel more "Doom" to me.
