If Halo: Combat Evolved was released on the Game Boy Color, it might look something like this. The 3D first-person shooter has been transformed into a 2D top-down game by SofaSwordsman using GB Studio, which is essentially a drag-and-drop game creator for Game Boy games.
Players still assume the role of Master Chief, a cybernetically enhanced supersoldier, and accompanied by Cortana, an artificial intelligence. This version has you battling 2D aliens as they attempt to uncover the secrets of the eponymous Halo, a ring-shaped artificial world. You can play it here now without having to download any emulators.

There’s something so special about demakes. To see everything created in the ‘realistic’ era of gaming built as the games that got me started-out. Part of it is the simplicity. I look at that MC and it throws me back to being a kid, when we had to imagine what our battles and adventures really looked like,” said a commenter.
