Zero Wing (Japan)

Zero Wing is a side-scrolling shooter that originally hit Japanese arcades in 1989, then landed on the Sega Mega Drive (Genesis) in Japan the following year. The game was developed by Toaplan and published by them for the Mega Drive, though Western gamers mostly know it from its infamously broken English intro text. On the Genesis it's a straightforward port of the arcade shmup, with the same wave-based shooting action and a minimalist story about a villainous CATS organization.

You control a small starship that scrolls automatically from left to right while enemies appear from all sides. The core loop is simple: shoot everything that moves, dodge incoming bullets and obstacles, and collect power-ups that upgrade your weapon. The game uses a weapon bar system where collecting specific icons changes your primary fire, ranging from lasers to spread shots. There are no shields or complicated mechanics - just your reflexes and a limited supply of bombs to clear the screen. Bosses show up at the end of each stage and require pattern recognition.

For a shmup collector, Zero Wing is worth a look mostly for its historical notoriety. The gameplay itself is functional but unremarkable compared to contemporaries like Thunder Force or Gradius. The Genesis version runs smoothly and has decent music, but the real draw is the butchering of English in the intro sequence that became an internet meme. If you're after solid 16-bit shooting action, there are better options, but if you want to see the game behind the 'All your base are belong to us' meme, this is it.
