Today, Black Mesa finally comes to Steam after being Greenlit on Steam so long ago.

Black Mesa , the mod that set out to recreate the original Half-Life from the ground up in the Source Engine has had a long and exciting journey from the days when it was just an ambitious idea.

Black Mesa is a now a full on game and is priced at $20 USD, it’s considered ‘Early Access’ for now, so things like Xen and more multiplayer modes are still to come. Of course anyone who buys now will get those features for free when they release in the near future.

When Xen does finally become available the price will be bumped up to $25 USD.

The Steam release has multiplayer and Workshop support, so expect to see some custom made Scientist Slaughterhouses in the near future.

There’s also a launch trailer, which replaced the countdown clock shown on the mysterious bmrf.us website, made by Source animator James McVinnie. Check it out:

The developers are also doing a live stream event on Twitch later today to celebrate the launch.
