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.
Good game, but not really innovative and not so atmospheric as original and even Ep1 (what can be more epic than destroyed Citadel?). Although, some time before I liked Ep2 more than Ep1, things changes, and I can't preffer one over other right now.
