Alateron will join Iceborne at July 9th!
Capcom announced Fourth Free Title Update schedule just ago. It will be July 9th and before the update, Developer Diary 6 live stream will be at July 3rd. The trailer includes a few patterns of Alatreon & New fest, new layered armor which looks Kelbi's head (probably obtain from new fest quests)
About a month ago, there was a leak of Barioth variant. The last moment of the trailer showed Barioth's eyes and roar. Well, now it's obvious that the leak was real. Check this video to see detail. I've been waiting for Alatreon so long. I cannot wait even Developer Diary!
