I think the number one was DUSK. I initially put it off as just another boomer shooter trying to “ride the wave” of the trend, but after giving it some time to get past the first few levels, it really is more than that. It’s sort of a combination of the “badass” gameplay of Doom but with a horror story and atmosphere. There were truly some terrifying moments in the game, and a lot of the levels a pretty nightmare-fuel. The low-poly aesthetic sort of turns this up a notch in a way.
It has this very refreshing gameplay loop where part (or multiple parts) of a level will be a typical boomer shooter focus on gunning down hordes of enemies or even a boss fight, while in the meantime you’re navigating a labyrinthine environment with some pretty terrifying imagery. A lot of the story is implied during the levels and then explained in between levels through text, so the player is really left guessing for a lot of the game, and the story opens up far more than one could ever expect.
A lot of people may go into DUSK expecting Doom or Quake or even a more modern game like UltraKill, but I think it’s a lot more than those three combined.
