So I'm playing the Masterchief collection, going through the playlist mode, level by level. I happen to be on the level "Keyes" on Halo: CE. Quick reminder for anyone: Keyes is the level where your looking for Captain Keyes on board a Covenant Vessel after finding out that Halo is a weapon. The level is filled with both Flood and Covenant enemies. So as soon as the mission starts, I notice a tiny little window to the side and what do I see? The Flood cacoon that holds Captain Keyes corpse in the distance. So basically, you start the level in the hallway next to where Captain Keyes is being held and you spend the entire level looking for him? Yeah the door is locked and all, but it has no problem opening when the Flood attack after reaching him. Bad level design? or is Cortana a lousy navigator?
