For context: a "Boomer Shooter" is a style of FPS that helms several qualities that align them with 90s era shooters. These qualities include (but are not limited to): chunky 3D models, sprite models, maze-like level design, large combat arenas chuck full of enemies, key hunting, and so forth.

This list also includes games made within the modern FPS era where they're inspired by the classic "Boomer Shooter" style.
