Dolls Nest

Dolls Nest is a PC (Steam) action game from Nitroplus that is expanding in late 2026 through a free October update adding the Combat Test mode and a PLAMATEA plastic model of the Unknown Armored Soldier enemy now on preorder. The game is playable at Tokyo Game Show 2026 ahead of the retail update.

Synthesized from 2 Yomimono stories · updated Sep 17

Dolls Nest is a 3D action game from Nitroplus released on PC via Steam in 2025. Coverage of the game centers on two September 2026 developments: a free major update and a plastic model kit based on one of its enemies.

On September 10, Nitroplus announced that a free major update would arrive in October 2026, adding a feature called Combat Test. In Combat Test, players fight training units in arena-style content, and a combat skill grade rises with the number of units destroyed. Reward items are distributed according to that grade. A trial build of the feature will be playable at Tokyo Game Show 2026, though that build differs from the retail version.

Four days later, preorders opened for a PLAMATEA assembly-type plastic model of the Unknown Armored Soldier, the enemy that stands in the player's way in the game. The kit is listed on Rakuten Books at 11,031 yen including tax against a reference price of 12,799 yen. It includes the assault rifle AR102 A2 Gladius, the railgun Femt, and ML32v5 Cetus missiles, along with a stand and interchangeable hands.

The two stories point in the same direction: Dolls Nest content is extending past the base game into repeatable arena fights and into merchandise built on enemy designs rather than the hero. The October 2026 update and the model kit preorder are the current markers of where the game stands.
