New Ceres forest
New Ceres is a planet with the recreational colony where Kal Wardin spent his retirement before the events of N.O.V.A., when he resumed duty. After destroying Colonial Pride, Kal returns there on an escape shuttle, landing in the outer jungle, where other Marines hold out against Xeno forces and directed him to the Epsilon bunker - old enough that it was "not used since rebellion times". There, he clears out the Xeno forces inside and averts a nuclear launch, then escapes the base on a 4x4, then takes a shuttle to a mining facility elsewhere on the planet overrun by corrupted marines. Once the problem is resolved, he leaves the planet through a portal he is told to go through by Prometheus, leading him to a monolithic city on a Xeno asteroid.
