Thanks! Sure, all characters have same abilities as in original LotR:C, no rules were changed.
I tried to make them look as close to Half-Life lore as possible, though. For example, Combine Dropship (Shelob) returns to Overwatch Nexus, where they loaded troopers in the videogame. Tunnel of Moria is now Underground Railroad (safe route for City17 refugees), and Metrocops can block it and kill everyone, as they did in the game too. Colonel Odessa's squad had RPGs, so it can destroy Hunter Chopper, etc.
