Capcom has detailed the additions coming to Monster Hunter Rise: Sunbreak - including the weather-manipulating elder dragon Amatsu - as part of its free April update. It's also confirmed there'll be one final free Sunbreak update arriving in June.
Monster Hunter Rise's Title Update 5 (also referred to as Version 15) launches tomorrow, 20th April, and its most notable new arrival is the Looming Calamity, better known as the elder dragon Amatsu. This formidable creature can control the weather, conjuring violent storms and lightning strikes once it shows its true power, and is available to hunters at MR 10 or higher.
Amatsu is accompanied by Title Update 5's second creature addition, a powerful Risen variant of Shagaru Magala, which becomes available at MR 180 or higher. As you'd expect, new equipment can be forged from the materials dropped by both creatures, including a fetching Palamute outfit resembling a floating armoured horse.
