Columbine happened in the 1990s. I remember when they came out with the DOOM map for it. In the 90s. I never actually played it, but I kinda wanted to.

I feel like if Blood came out after Columbine, they would have had a school level. They did have a grocery store level. Blood was more like Duke Nukem 3D, way more advanced than DOOM, but still that same generation (what people now call boomer shooters).

There are some delicate snowflakes who are pained to leave their safe room echo chambers if content like this exists in the world.
