I played Zero Wing at a friend’s house for the first time two days ago after growing up with the All Your Base Are Belong To Us meme. My friend is one of the few I know with NSO+ and I booted it up with the intention of only playing the first level when we were in between things, but the four of us there all got into it and beat the game (with rewind). I don’t think I ever saw footage of the game beyond the infamous intro cutscene and while I knew it was a side scrolling shooter I don’t think I ever saw it in action. The most interesting gimmick with it is once you get your first power up (there’s the basic spread, homing, and power shots that level up as you get more) you’ll immediately get two drones that fly above and below your ship and they are weirdly invulnerable. Like a laser won’t just pass through the drones, they’ll stop it altogether. If you go through a narrow passage the drones will clump up with you. You also can pull in enemies to use as a shield, but it’s kind of finicky. Anyway it was a good, brief time and the ending with some dancing eggpplant dudes was very unexpected haha.
