Retrobooster’s junkyard ships thrust, spin and blast their way through hazardous caves, all the while spewing extraordinarily impressive particles. Activating a thruster to stabilise, even if there’s only the slightest touch of a button, and the air fills with fumes. Bombard an alien and its mechanical walker erupts, debris scattering, flames billowing. Creator Terry Welsh, formerly of NASA, has this to say about the in-development title: “Piloting a ship that is always seconds from a fatal collision, Retrobooster sustains a quiet tension. Survival is between you, the alien horde, and the game’s realistic physics.” The demo contains plenty of fatal collisions and a sensible person would probably download it immediately. Trailer below.
