Next Level Games was indeed working on a Metroid title, if a “trusted source” is to be believed. The source, who was reportedly involved with the unannounced project, told Destructoid that Next Level Games made a Metroid prototype before it began development of Luigi’s Mansion: Dark Moon. Concept art for the supposed prototype was recently spotted online.
“Yes that is real,” the source said. “That’s the first I’d actually seen of that concept art, but a prototype was made before being shelved in favor ofLuigi’s Mansion 2. It was about as bare-bones as it gets, but it was still pretty fun.”
