I never played SS either. I would have if I knew it was this amazing piece of history in gaming, but it kind of just flew under the radar for me while I was playing more standard shooters like Doom, Hexen, Heretic, ROTT, Dark Forces.
That new trailer looks just like a standard survival horror indie game. The voice is nice but over the top. The design just looks like copy/pasted corridors. The combat looks awful. It's not even clear when you hit the enemy, they're just standing there button mashing.
Although, I didn't mind that main theme after listening to it as a comparison to the old one

That's pretty sweet. I'd rather have that over my game then some thrashing techno giving me a headache. Maybe I'm getting old.
