Chicken Invaders 4

Chicken Invaders 4 launched on June 6, 2014 and has remained under sustained development ever since. The most significant recent milestone was the free "Episode 4" major update on January 9, 2025, which fundamentally overhauled the game with remastered Full HD graphics, a new engine, reworked weapons, new game modes (including Endless mode), built-in seasonal content, and features back-ported from Chicken Invaders Universe. That update also noted that language translation work was "still ongoing" with improvements expected in future updates. Since the Episode 4 overhaul, the developer has continued shipping feature updates at a steady pace: v.20 on January 16, 2025 added a loading screen and letterboxing options; v.21 on February 20, 2025 added local two-player support and Steam achievements for the Episode format; v.24 on August 12, 2025 added accessibility settings and cheat unlockables; and most recently, v.35 on September 26, 2026 introduced multiplayer support for the Episode format along with improved Steam Remote Play Together support and working Steam achievements. The developer has not announced the conclusion of development. All three seasonal DLC packs (Christmas, Easter, and Thanksgiving editions) have been released. The Linux native build was discontinued in late 2021, with the developer recommending Steam's Proton compatibility layer as an alternative, but Windows and Mac support continues.
