Archie Comics once entertained the idea of making a series based on Metroid. In fact, it went so far as to commission artist Steven Butler to draw up some concept art.

Nintendo will re-release the original Metroid game on the 3DS eShop this week.
After what feels like a wait of ninety million years, this week finally sees Metroid Prime 3: Corruption reach our Euroshelves.
