A new report from a credible insider alleges that Microsoft may be working on a Halo: Combat Evolved remaster which could make its way to PlayStation 5. The company shifted gears on its exclusivity strategy for Xbox earlier this year, porting four back-catalog first-party titles to PlayStation and Nintendo platforms. Although Microsoft Gaming CEO Phil Spencer assured fans that the initial batch won't "open the floodgates" for other games, speculation has run rampant around which games could go multiplatform next, and it appears Halo: Combat Evolved the kickstarter of the Xbox brand is one of them.
