Overwhelmingly positive reviews out the wazoo. I found out about it here:

It’s Id’s early aesthetic (eg. skulls) boiled down into an arena shooter. It’s also cribbed Id’s early weapon design (shotgun and lightning gun, specifically), merging them together into the player’s hand, which sprays red death at a growing mob of enemies (eg. skulls) that are chasing after you and the strange obelisks that birth them.
I haven't tried it, but it looks like a very dumbed down Doom/Quake with no stages, just endless enemies and a scoreboard. So of course, RPS game of the year 2016.
