All New Missions in (Valley IV) Arknights Endfield version 1.0

Last Updated on February 4, 2026 by SoraHoshina

Hello Endministrators! Arknights Endfield has finally been officially released as of January 22nd, 2026. This new gacha game is not an open-world game like Genshin Impact or Wuthering Waves, but a semi-open world that allows you to explore with some restrictions. Consider it like Honkai: Star Rail with their maps, especially the no-climbing part.

Nevertheless, the maps are big enough for you to get hundreds of treasure chests and other collectibles! In addition, the missions. Lots of missions. This guide will list out all the new missions in Valley IV, focusing on the Exploration Mission and Side Mission in Arknights Endfield. Main Mission, Event Mission and Commission is not included here because they are pretty much will always be available on your Mission Menu when it’s time to complete it.
