"" opens with Alyx and Freeman discovering that the Citadel's destruction has resulted in the formation of a super portal to the Combine dimension, which is slowly progressing to a stage where the Combine can send overwhelming reinforcements. They also discover that the data packet in the message they retrieved from the Citadel contains codes that can be used to close the portal, and so traverse the countryside to deliver the packet to the resistance headquarters at White Forest. As they progress, it becomes evident that the Combine Advisors escaped the Citadel's destruction, and that remaining Combine forces are regrouping, albeit under occasional attacks by Vortigaunts. Aware of the resistance's plans to close the super portal, the Combine attack White Forest in force, but are repelled. The super portal is destroyed after the resistance launch a satellite containing the appropriate data. However, in the game's closing scenes, two Advisors attack Freeman, Alyx and Eli Vance, and kill Eli before being driven off by Dog.
