Cinder City has opened applications for its next closed alpha, with the UK included among the eligible countries. NC and BIGFIRE GAMES are planning the Steam test for 4-6 December 2026, following changes informed by feedback from the earlier pre-alpha.
The developer says almost 3,000 pieces of feedback helped identify where the game needed work. The result includes new guide missions, changes to ammunition availability and a revised early difficulty curve, alongside additional areas and missions.
One of the largest additions is an expanded open world. The announced playable space grows from 1.2 by 1.2 kilometres to 2.4 by 2.4 kilometres, making the total area four times larger rather than merely doubling it.
Two new squad dungeons are also planned, alongside story content continuing into Chapter 3. New dungeon save points should let groups resume their progress instead of restarting the whole encounter, a useful concession when a promising session ends with everyone staring at the floor.
Combat changes include more ammunition drops, additional ways to recover supplies and a shoulder-swap option. The developers are also refining movement and melee feedback while making enemies in the open world more responsive to players taking cover.
Applications run until 30 November, and the official eligibility requirements include being at least 18. The UK, France and Germany are the listed European countries, with separate arrangements for eligible territories in North America and Asia.
The advertised 4-6 December dates use Pacific time. Regional session hours vary, so UK players should check the official information before planning their evenings rather than assuming those dates describe the same local play window everywhere.
This is a closed test of a game in development, with places selected rather than guaranteed. The public developer announcement explains eligibility and regional arrangements, while the Steam page has more on the shooter itself.
