• Update 1.4 - 8 August 2026

  Hello everyone,Update 1.4 is here! This time, the main focus was on polish, balancing, and optimization.1. Rework of old rooms and hallwaysThese areas of the map were very outdated and visually jarring. They have now been reworked to match the quality level of the latest map expansions.2. Nightmare Mode reworkI completely redid Nightmare Mode. Enemies now spawn based on the room you are currently in, instead of using the old system, which was purely distance-based.The old system had a major flaw: if the player stayed in a room with small doorways for a long time, drones could spawn in other rooms and never reach the player because they couldn't fit through the doorways. Since they couldn't reach the player, they would never be destroyed, causing more and more drones to spawn endlessly. This would eventually fill up the rooms, consume a lot of memory, cause the game to lag, and make thos…

• Update 1.3 - 18 June 2026

  Hello everyone!It's been a long wait for you and a lot of work for me, but I can confidently say that the 1.3 update is finally ready. It includes a new map expansion, a new monster, improved enemy behavior, performance optimizations, and many other fixes and improvements.1. Reactor Sector ExpansionThis took the most time and effort to create, and it's by far the biggest addition in this update. The Reactor Sector has been completely redesigned and expanded, including a main hall, control room, storage rooms, and connecting hallways.This sector acts as the finale of the first level (Prison). Once completed, it will unlock an elevator leading to the next level (Sewers), which will be added in the future updates.2. New Monster: Fatty!Fatty is huge, slow, has a lot of health, and deals massive damage - basically a tank. It can also shoot acid balls that explode on impact, leaving behind ac…
