Remember how it was said the demo was coming soon? Well, soon is this week.
In a PR email sent by Nintendo UK, which details things like Lola Pop for ARMS, new Splatoon 2 content and even new Heroes for Fire Emblem Warriors, it is explicitly stated that the demo of Pokkén Tournament DX becomes available this very week and we have the direct quote for such news right here:
Nintendo Switch owners who want another dose of combat should also be on the lookout for a downloadable demo of Pokkén Tournament DX, coming to Nintendo eShop this Thursday.
If you are on the fence about picking the full game up next week, the demo will help you with your decision.
