Selaco is the sleeper pick on this page. It is a retro FPS built on a GZDoom foundation with level design that rewards exploration and firefights that feel genuinely tactical rather than just frantic. The enemies use cover, react to sound, and do not behave like the cannon fodder you expect from the aesthetic. It sits in honorable mentions because the broader accessibility is lower than the top-ten picks and it is still in early access, but shooter enthusiasts looking for something with more thought behind the combat design than the average boomer shooter should look at it.
