Yes, but without mods, non-lethal options are a joke to use. Some will probably disagree with me, but I'd recommend playing it with the Revision mod. It improves so many aspects of the gameplay, and just makes it feel less janky, and more modern (in good ways).
It's a great game and you should play it, but it's definitely an old game without a lot of the quality of life improvements afforded to us in the modern era.
Remember to save early and often, and also in multiple slots
Thanks for bringing this up. I got a steam deck OLED and for some reason the OG Deus Ex was in my long-stagnant steam account. I think I bought it in college when I was playing around with windows partitions on Mac with boot camp. I guess now I can see about putting in a mod to modernize it a little and play it. I love playing older PC games that I never had access to in childhood.
I haven't tried to play hl1 again, but Morrowind is amazing and the modding community is amazing, I clock a good 200 hours every time, and I still went over a hundred thirty on a vanilla playthrough four years ago.
