This is a first chapter of RtB:R mod.
Experience Half-Life 2 like never before. Return to City 17, held within the iron grip of the Combine and the Consul. Reunite with old friends, and enemies, and some of them brand new. Immerse yourself in a revitalised combat system featuring old arsenals made new again, with added features to raise the bar in gameplay. You've been waiting for quite some time, now. It's time to climb aboard.
