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.
A marvelous mod from the early days of Half-life 2 modding.
It really felt like the whole place was coming down on my head as I progressed further and further through Rock 24, with impressive mapping and plenty of nifty details and voice-acting.
Apply a fix, and give this a go as soon as possible! :D
