I’m going into Campaign Evolved with an open mind—expecting different, but not necessarily better. Halo Studios’ official playthrough of mission five, Assault on the Control Room, is so far confirming that impression. I watched the 28-minute video in full and then played the original mission through the MCC to refresh my memory. What follows are some notable differences and observations:

“These lights seem to be responding to our proximity and guiding us to the exit,” a new Cortana voice line says as Chief enters the first of many hexagonal control rooms. It could be a little confusing to find your way around these rooms in the originals, but l always found the flashing white arrows on the ground pointing forward to be sufficient visual guidance. Now, Cortana barks that tip into your ear so you can’t possibly miss it.

Not that you actually need to look for arrows on the ground when Campaign Evolved has added HUD waypoints that are visible at all times. This is one of several ways that Halo Studios’ is applying a modern hand-holdy lens to Combat Evolved.
