What is a Shoot Em' Up? Defining the Genre with Shmup Junkie. This video  has literally been years in the making. As much as we all the love  Shoot Em' Up (shmup, STG) genre, what's embarrassing is that, up to this  point, over all these decades, there has never been a solid criteria or  definition of what a shmup even is. For a genre that is so fundamental  you'd think this would have been established by now, but due to the  nature of online discourse, this question has never been resolved. Over  the years, I have worked on what I think are the 3 criteria of what I  believe consitute a shmup, and in today's video I explain these criteria  and run them by fellow youtuber, Shmup Junkie, to hear his reaction and  thoughts. We not only talk about shmups, but also related genres like  run n' gun, rail shooter, gallery shooter, first person shooter (fps),  third person shooter, single screen games, metal slug, contra,  platformers, twin stick shooters, Star Fox, Doom, and many more! I think  we have a fantastic discussion and I do think this is one of the most  important episode of The Electric Underground :-) I am now going to list  off some algorthym tags: Nintendo Switch, Steam, Bullet Hell, PS4. PS5,  Xbox, PC, Indie, Hidden Gem, Sega, CAVE, Touhou, Battle Garegga,  Longplay, 1cc, Podcast.
