Radix mod for Half-Life, Steam version. Unzip to the Half-Life directory to install.
You are thrust aboard the Top Secret Research Ship USCTS Chanticleer. Exactly what type of research takes place on the Chanticleer, or if indeed it is even a research ship, is unknown to all but the highest echelon. But you are about to find out first hand what secrets are aboard the Chanticleer, as you set in motion a chain of events the likes of which the post-Black Mesa world has never even imagined.
