Reading through this stuff, everything seems fine. Everything except how movement is covered. Ordinarily something like D&D uses a grid along with 5-foot increments to measure a characters movement within' a round. This mentions something about zones and the like, kinda weird.
Outside of D&D and Pathfinder, i think rules for movement can vary. I know the Star Wars themed RPG's don't use grid based combat, and just have different distance measurements, the same for the Legend of the Five Rings RPG, and The One Ring. It depends on the game and the DM playing the game, i've had D&D sessions where you don't need a map for combat, it just makes it easier.
Reading through the Starter Guide, and just envisioning how the game could play, i don't think it would really work too well to use a grid based combat system in an Alien universe, where generally speaking you aren't really going to be fighting lots of enemies at once, and if you are, you're probably pretty screwed.
