Evaluation
Boxhead: Immortal has been in Steam Early Access since March 27, 2024. After an active launch window — with feature patches in April 2024 and a major multiplayer update on May 29, 2024 — development ran into serious trouble.
On March 30, 2025, the studio published a briefing disclosing that its core development team had been restructured and replaced, causing slow progress during a difficult handover. The post previewed upcoming content (new weapons, characters, enemy types, UI improvements) and stated the project was back on track under new leadership.
Then on August 31, 2026, after an extended period with no updates, the studio published another status post explaining what happened next: the replacement programmers also proved unable to handle the work, and the current programmer describes the existing codebase as "very messy and non-standard," requiring a full refactor rather than incremental additions. This means the studio has assets ready but cannot put them into the game until the underlying code is rebuilt from scratch.
The August 31, 2026 post confirms the studio is still active. In a best-case scenario, they plan to release some content later in 2026 for testing, with a larger content drop targeting spring 2027. They also promise that all players will receive the first paid DLC for free after the full release, as compensation for the delays. On September 30, 2026, the studio posted its first monthly devlog, previewing new map designs and committing to monthly development updates going forward.
The store description continues to note that Classic Mode and Campaign Mode are still under development. Two successive team failures and a codebase requiring a full rewrite mean the stated timelines carry real uncertainty, even though the studio has recently resumed regular communication.

About this game
A certain zombie virus arrived on BOXHEAD World with a meteorite that fell by chance, causing the cells of many people with Type B blood to merge with the virus, quickly turning them into zombies. To survive in this purgatorial world, you must unleash every bullet into the hordes of the zombies and use any explosive objects at your disposal to drench every inch of the land in blood.

1:1 replica of the details in the previous Boxhead games. This brings the original nostalgic experience!
In Classic Mode, there are 4 skins for you to choose that comes along with the classical maps with various layouts. Changing a map gives you the feeling of a brand new game. You can also get other useful weapons and props by picking up red boxes.
Endless Mode

While retaining the classic core gameplay, the mode has undergone bold innovations. Rogue elements have been appropriately added to enrich the playability and replayability of the game. Before starting a game, players can not only choose from their own skins for their characters but also select from four different roles, each with multiple unique skills and attributes for players to mix and match. Additionally, there are several newly designed maps available for play.
Campaign Mode
Everything seems to start from the meteorite, or the government. Who knows? However all this does not matter with the problems you are facing - surviving is much more important.
Following the storyline, players will break through the zombie hordes step by step, then advance into cities overrun by the undead, and ultimately unravel the mystery to resolve the world crisis. This mode features multiple meticulously designed large maps, where players can explore, upgrade and customize their equipment, and eliminate wandering zombies.
