Are boomer shooters the successors to run 'n' gun games? Because they share quite a lot of similarities honestly. Both rely on fast movement, good aiming, insane larger-than-life bosses, bizarre over-the-top guns and lots of weapon pickups scattered around the level. Some run 'n' gun games even have secrets, although they don't require you to pick up keys or solve puzzles, that's pretty unique to boomer shooters.
>>37139>First person shooterThis is a broader genre, not the actual subgenre. It's like calling run 'n' gun games shmups: sure, you're technically correct, but Contra is not the same thing as Gradius, they're totally different. Run 'n' gun games are closer to boomer shooters than they are to other shmups. The alternative names for boomer shooters are "retro shooters" and "old-school shooters." Which is confusing since you also shoot at enemies in shmups but those genre names were always kinda stupid, I think a more accurate name would be "retro FPS" and a proper classification would put both FPS and sidescrolling shooters under the shmup label. But alas.
