As you may or may not already be aware, Monster Hunter World has nuzzled up with the Northern Kingdoms today, as part of its Witcher crossover. Previously, Capcom was a little cagey regarding the specifics of the update, but now, with things underway, all has been revealed.
First things first, it's worth noting that Monster Hunter World's free Witcher crossover update is only available to download on Xbox One and PlayStation 4 at the moment. It is, however, due to arrive on PC at some currently unspecified future point.
Capcom's Witcher crossover is split into two separate parts. The first, a new Special Assignment known as Contract: Trouble in the Ancient Forest, is a wholly solo affair and casts players (as long as they're HR16 or above) as Geralt of Rivia - with voice actor Doug Cockle even returning to record some new lines for the project, as you can hear in the launch trailer below.
