Monster Hunter XX: Double Cross will not release in Europe anytime soon, Capcom has confirmed. The developer has decided to not localise the Japanese adventure game "at this time". The updated version of the 3DS game Monster Hunter Generations was announced for Nintendo Switch a few weeks back, but unfortunately, that won't make much difference for European players (unless they can read Japanese, that is). If Capcom changes its mind, we will keep you updated. With that in mind, it looks like Monster Hunter World is your best bet at the moment.
Thanks, Gamespot.
