Prepare yourself for an engaging first person shooter experience unlike any other. Eternal Silence is a Cinematic Multiplayer Space Mod built on the Source Engine. It has been in development since 2003.

A massive deep space artifact from long-gone Earth was found and spawned a renaissance on the human colonies of the United Terran Forces. A gigantic assault from the UTF on the now independent colonies spawned the Neo Galactic Militia and started a deep space war the likes of which the world has never seen. Your role in Eternal Silence will be within vital strategic battles between massive capital warships. You will need your wits, your precision, your strength, your endurance, and above all your courage to take on the fierce challenges which await you.

Note: To play Eternal Silence, you must own Half-Life 2 and have the Source SDK Base installed. (Having Half-Life 2 installed is NOT a requirement.)
