Story: HL2 mod continuing story of HL:Opposing Force character Adrian Shephard in a time set somewhere between HL1 and HL2. It brings you from a Black Mesa like base trough an outdoor environment and a Soviet marine base into a early combine citadel to end in a ancient alien location here on earth, the combine stumbles upon when creating a citadel. What you get: Intro and 5 playable maps roughly good for a hour of playtime. The mod includes custom props, textures and music but NO new weapons or NPC's.
A great single player mod overall. It only has about 5 chapters but very fun and enjoyable and a great way to expand the half life 2 story.
