This is the first major chunk of Monster Hunter World in English. It's commentated by a Capcom representative, but it's a great explainer on exactly how Monster Hunter works and you get to hear what the English voiceovers are like as well.
The video is basically a walkthrough of hunting a new monster called an Anjanath, from the initial footprints to the final fight. It goes through the little hub area where you can restock and rearm, the basics of tracking, distracting monsters with sound, multiple fights, getting help from the environment and more.
If you've ever wondered what is Monster Hunter, this is actually a really good little primer as to how the gameplay flows.
Monster Hunter: World is due out on consoles early 2018, with a PC version scheduled for later in the year.
