RocketWerkz, the studio behind DayZ, is building Kitten Space Agency, a space‑flight sandbox billed as a spiritual successor to Kerbal Space Program. The project brings together former SpaceX flight software engineer Stefan Moluf and original KSP creator Felipe Falanghe, alongside founder Dean Hall. Moluf says the game will let players design rockets, launch them, land on alien worlds and explore, all while exposing real engineering constraints.

KSP2’s troubled early‑access launch taught the team hard lessons about technical debt. Moluf argues the new engine, a low‑level framework called ‘Brutal’ built in‑house, gives KSA a cleaner foundation, eliminating the patchwork architecture that hampered its predecessor. Faster scene transitions and seamless movement from Earth to other planets aim to remove the long loading times that plagued KSP2.

Modders will shape KSA from day one; RocketWerkz hired two prominent KSP community artists to ensure mod‑friendly pipelines. The current pre‑alpha runs on placeholder assets in a fictional solar system, focusing on flight physics rather than polish. Although the interface feels technical, the core systems already demonstrate the intended depth, confirming the studio’s commitment to a more stable, extensible space sandbox.
