Halo: Campaign Evolved hits Xbox, PC, and PS5 today at a synchronized global time, ending the Premium Edition early access window that started July 23. Standard Edition and Game Pass players waited it out while Premium owners got the jump, but no New Zealand rollout means everyone's on the same clock.

The remake runs on Unreal Engine 5 with upgraded visuals, three new missions, redesigned levels, and mechanics pulled from later Halo entries. It supports full cross-play and cross-progression across all platforms via linked Microsoft accounts, plus up to 4-player online co-op and split-screen on consoles. Day-one Game Pass Ultimate and PC Game Pass availability is locked in.

X is already lit with Cortana cosplay, NVIDIA Game Ready drivers dropping DLSS 4.5 support, and players hyping the launch on Xbox, PS5, and Steam. Early reviews from places like VGC and Polygon are calling it a strong return to form.

This drops on the exact anniversary-adjacent timing the franchise needed, and the multiplat push plus Game Pass day-one is the real story here.
