We don't have any info about the story at all and I wouldn't really describe this game as Halo 4, but it is probably closer to a prequel.
It most likely is a prequel, because of the name Halo Reach. Reach was the planet were Master Chief was on before he and the Pillar of Autumn went through slipspace, which brought them to Halo, Installation IV.
Therefore it can be assumed that we play the Spartans (most of whom die) on the Planet Reach, one of Earth's devastating losses.
