The original Half-Life set the bar in so many ways for the first person shooter genre when it launched over 10 years ago. One of the things missing though was co-op play. And while there's plenty of mods that add this to Valve's classic, this brand new remake looks extremely promising.
The total conversion is a complete remake of the Black Mesa facility, the famous first level of Half-Life 1. The only thing required to play will be a copy of ANY source engine game - like Half-Life 2, Left 4 Dead, and others. The mod not only offers some slick visuals with brand new textures, but will sport a cooperative mode built in. There's no word on how many players will be supported.
For now, drool over the first trailer posted after the break.
