The latest version of
Obsidian Conflict is now locally mirrored, allowing you to play this
Half-Life 2 modification where you are a former prisoner of Earth, taken from your cell to a Combine Research facility in the arctic. There in the dome used to generate their huge holographic worlds, you are faced with a challenge. You have been placed in a holographic space so realistic that you can't tell the difference between the real world and the fake. Visit the official
website for details.
