BERG

Co-op games about survival, physics, chaos, voice mechanics, teamwork, and the tiny disasters that make playing with friends unforgettable.
Hi, I’m Alex — a solo developer from Germany and the person behind ZweiBier Indie.
I have always loved games. Before starting my own studio, I worked as a Unity developer, building the experience that now helps me create my own projects independently.
For me, game development is not just a job. It is a dream, so I never get tired of building worlds, testing mechanics, breaking prototypes, and turning strange ideas into playable co-op chaos.
