G.I. Joe - The Atlantis Factor Game

"G.I. Joe: The Atlantis Factor" for the NES is a hidden gem that takes the classic run-and-gun action of the G.I. Joe series and cranks it up with deeper gameplay and a killer sci-fi twist. Instead of just blasting through enemy hordes, you’ll pick from a roster of iconic Joes—each with unique abilities—to navigate challenging levels, uncover secrets, and take on the villainous Cobra in their underwater Atlantis stronghold. The side-scrolling action feels tighter and more strategic than its predecessor, with cool power-ups and even vehicle sections to keep things fresh.

What really sets this one apart? The Atlantis theme adds a fun, almost Captain Nemo-esque vibe, mixing high-tech military action with mysterious ruins and underwater bases. It’s tougher than your average NES shooter, but that just makes unlocking each Joe’s potential even more satisfying. If you loved Contra or Metal Slug but wished for more character variety and a dash of retro sci-fi, this underrated title deserves a spot in your lineup."
