Black Mesa: Source video shows renovated On A Rail mission in action

Some leaked footage claiming to belong to the elusive Black Mesa Source mod has appeared over on Valve Time , showing some classic weapons and environments renovated in Valve's Source engine. The video shows a bit of violence from the 'On A Rail' mission. But for the odd detail, like iron sights aiming for the Magnum, it all feels very familiar, albeit a fair bit prettier than the original. Take a look.

The footage follows the official release of some new Black Mesa Source screenshots back in June. The mod's been in development for many years and hardly anything's been shown, until now. What do you think?
