The surprises are new weapons, new vehicles, and a brave new world - one that’s been a part of Halo lore from the very beginning. When the Forerunners were building Halos to stop The Flood, they also built Shield Worlds to protect their civilisation and others from the 25,000 light year-range of the seven Halos’ blast.
