Monster Hunter XX will not be getting an e-Shop demo for Nintendo Switch.
In an interview with Gamecores in Hong Kong, Producer Mr. Kojima confirmed that Monster Hunter XX won’t be getting a demo on e-Shop because it’s already available to try out in many parts in Japan.
Q: Will there be a demo released (to eshop)?
A: We won’t release the demo, because you can already try Switch in many part of Japan, and MHXX demo will be available on site, sorry about that.
