It’s also timeless in that, before “Halo: Campaign Evolved,” “Halo: Combat Evolved” had already been remastered as “Halo: Combat Evolved Anniversary” in 2011. Due to the Xbox Series X’s backwards compatibility features, you can also play “Halo: Combat Evolved Anniversary” and the original Xbox’s “Halo: Combat Evolved” on an Xbox Series X. Not only that, but “Halo: Combat Evolved Anniversary” is included in the “Halo: Master Chief Collection.” With three alternative and cheaper ways of playing the original Halo Campaign, “Halo: Campaign Evolved,” Xbox, and Halo Studios (formerly 343 Studios) were facing an uphill battle from the outset. Likewise, veteran Halo players are going to be disappointed as well because it’s just a worse version of “Halo: Combat Evolved,” with new content that only makes the future of Halo more uncertain.
