The 'Halo Infinite' campaign is the closest to perfection in 20 years

There are two possible disappointments with the campaign. First, there is indeed a lack of biome diversity, as some fans feared based on early previews. In terms of lore, Zeta Halo is the largest and most ancient of the ringworlds in the series. In terms of game design, "Infinite" is also the largest a Halo game has ever been. Still, players are restricted to one portion of the ringworld, largely peppered with trees similar to those you'd find in the Pacific Northwest, along with swamps and mountains.
