 In an early version of the game script, Gordon was to receive a  briefing by Eli Vance via slides to fill him in on what had happened  in between the large gap of time he had been gone. The slides would  have featured Bullsquids chasing people from their homes and an  Icthyosaur materializing in a public pool under a kid halfway  through a dive. It also set up how the combine was able to gain  power. It would have ended by showing Dr. Breen and the power he  received. This was cut for pacing reasons.
