Black Mesa gameplay trailer leaked

The Half-Life remake mod Black Mesa really is coming, and now a leaked video confirmed as real has surfaced with a peek at its jazzed-up 'On a Rail' chapter. You know, that frightful section with the tedious trains then glorious rocket launch.

The footage leaked to ValveTime is a rough cut of a planned gameplay video the Black Mesa team put together, Black Mesa team member 'Raminator' has responded, which somehow got into the wild early.

"The build featured in the video is between four and five weeks old," he explained. "You won't be seeing very many changes between what's in the video and what's in the final product."

As for the iron sights aiming seen on the revolver, a feature not in the original Half-Life, that's only available for the .357 and crossbow, boosting accuracy a little but lowering firing speed. After fans grumbled about seeing this in the leaked video, an option's been added to disable it.

Raminator says that following the leak, the team is going to be "moving some things forward" when it comes to showing us more of the long, long, long-in-development mod.

Some frankly unwatchable footage of an early version of the 'Surface Tension' chapter has also been leaked, though darned if I can see anything in it.
