Bungie made Marathon before Halo and it's basically the same plot - supersoldier aided/hindered by AI/s fights an alien force consisting of many "integrated" species. It's a cheap way of making different enemies that are all antagonists.
OFC why the colony ship Marathon needed a supersoilder on tap is never explained. After a while our protag gets involved in a rebellion against the Pfor's leaders and then we get Infinity which is just weird. Oh and there's an eldrich horror living in a star too.
