As Dr. Gordon Freeman, you were last seen exiting City 17 with Alyx Vance as the Citadel erupted amidst a storm of unknown proportions. In Episode Two, you must battle and race against Combine forces as you traverse the White Forest to deliver a crucial information packet stolen from the Citadel to an enclave of fellow resistance scientists.
Just a map that i started one day and finished some time later. To install it just download the .rar and extract it in the main Half-Life 2 folder, the map is called "prisoncellep2_1"
This map does have potential but the bugs get in the way, unfortunately.
