The announcement post and related imagery have a Halloween/spooky theme, and with a name like Dread, it's certainly fitting of the spooky season. Nintendo didn't share any details on the limitations of the demo, but in any case, it's a nice option if you're curious.
GameSpot's Metroid Dread review scored the game an 8/10. "More than anything else, Metroid Dread feels like going back to a place of comfort after a long time away," reviewer Steven Petite said. "Though the gameplay is refined and new features have been added to the mix, Dread sticks closely to the formula of its predecessors. In the end, for longtime fans like myself, that's probably for the best. There's nothing to dread here. We're home again."
