Rock 24 takes place on an abandoned Cliffside prison. The prison is situated on the side of a sheer cliff face meaning the only real way in and out is by air. The combine have moved in to the facility and are re-using it as a place to hold rebel leaders and other important Rebels. Gordon is required to infiltrate, free the Rebel leader and hopefully escape from the facility alive. Unfortunately the prison is rapidly deteriorating around him and there isn't much time. Rock24 was in production for 9 months as a spare time personal project by two guys who work in the games industry. This is their first mod and attempt at level design.
Well, it was extremely painfull to get this mod working, but at the end it was worth it.I spent a whole saturday testing all possible solutions to make the npc animations on the mod work, after 9 hours of research when i finally found the fix/patch in a buried steam forum for broken mods i still had to deal with the fact that the first chapter of the game would necessarily crash as soon as the second chopper fall down and you would have to load the second chapter from the console, so it was another half hour of search until i find the damn command. However i won't discount the mod score because of the huge effort the author spent on fixing the mod after the HL2 Engine update. Anyway... the mapping on the mod is very innovative and filled up with minuncious details, things like starting the mod in a ship in the middle of the ocean or electrocuting a prison guard with the charged cell bars compensated the fact of the poor employment of the freeman character. The thing i mostly liked about the mod is that although mostly of the action occurs in a prison, there's not a single resemblance of Nova Prospekt in it, it's a underground prison with a complete new visual that offers a great experience to the player. The gameplay can very hardly be improved, there's a perfect employment of combine fights, and offensive creatures encounters, there's also a fair distribution of health kits and supply boxes that turn the game very balanced in terms of difficulty. The voice acting is amazing and the interactive events will blow your mind away. Environments are also pretty creative, i never imagined see elite combines being crushed by a giant rolling rock in the middle of a cave full of stalactites or finding a box full of PSPs in the middle of a strider fight.
My final score is 7,8 but please provide a fix/patch link in the mod page :)
