Welcome back Mr. Freeman, Black mesa is now available on Early Access, Black Mesa is what we had all hoped half life source would have been, a total re invisoning of the Classic brought up to date with higher definition models, textures and more.

Crowbar collective state. “Making a game with the scope and scale of Black Mesa is a massive undertaking. Back in 2012 we made the decision to release what we had completed up to that point, and were blown away by the community’s response, feedback, and improvements to our work. We want to keep that relationship alive and well by using Early Access as a tool for allowing our community to participate in the final phase of Black Mesa’s development.

In addition, our ambitions go beyond the original Xen chapters found in Half-Life. We have a standard of quality that we have to achieve. Early Access allows us to commit resources to bring you the remaining chapters with the quality that you expect.”

"We currently have the first ~85% of our single player campaign completed. For the last 15% we want to not only recreate it, but improve upon it to make it an enjoyable and memorable experience. We feel it will take us considerable time to get the last 15% up to our standards, and putting a time estimate on it would be a total guess.”

This EA release sees you playing over 10 hours of single player campaign. Multiplayer deathmatch and team deathmatch with 6 completely re-imagined Half-Life 1 maps on the Source Engine.

I see many improvements in the game, but also a few kinks:

-The scientist's ties act like they were drawn by a magic pencil and are trying to fly away.
-Crowbar is way to fast, and goes all over the place.
-Zombie attacks are abnormally quick, doesn't work well.
-MP5 world model is kinda low-res, contrasting the other world models.
-Kliner's face needs to be smoothed.
-Tau cannon's hose-thing get kind of jittery (not a big deal though)

It's a work in progress I know but I just want the bugs to be recognized.

Developers of BMS never check this comment section, you should go to their community forums.

Also the glock's world sound doesn't match the players sound and gluons lever animation isn't there.

Me thinks the free Black Mesa with the Surface Tension and On a Rail Uncut mods is better than the payed version without the Uncut mods.

I think the team knows about them, so who knows if they may eventually end up being official

Me thinks that Black Mesa, and the 250+ mods in workshop is better then the free Black Mesa with the Uncut mods.

not sure if intentional or not but 357 and crossbow ammo give double the amount than usual, also if you pick up the weapons for the first time you automatically get full ammo for it. not really good because these weapons are really powerfull and giving so much ammo for it is quite a bit unbalanced.

This is one of the best examples of how far a group of dedicated fans can go to create something grand and pay homage to something the love.

This mod is great, so many possibilities now that they can release on steam.

Even the voice acting is good... except when the dialogue is all cheesy and just plain silly.

So many ignorant people....

You do realize, that retail BM is not considered a MOD anymore, knowing they are transitioning it into an actual GAME?

a GAME, that receives regular UPDATES?

I can easily understand why the Xen chapter won't be in the mod version, knowing how producing and developing with hl2 mods works today, I've seen games gaining MUCH more stability thanks to the Greenlight platform because of the extra 'goodies' developers can obtain through this process.

It's so easy to understand... But people have become so greedy and ignorant these days.... <.<

I'm a little disgruntled that the final build rings up 20 bucks but considering all the original modeling and scripting and voice recording implemented, one can conclude the devs deserve some compensation.

Game of the year in my opinion.

They deserve more than $20 they deserve at least $60 or $40. And it's not really what you should say final.

Well, think about it for a second. Think of all the mods that were released that were built from the ground up and got no pay for. Black Mesa had a lot of promised release dates they never fulfilled, Talk about broken promises. Becoming paid all of a sudden (in the eyes of the user who doesn't read the forums) is very interesting. They need to modify the engine anyway to make Xen possible, so it makes sense to cost money now. I never really cared for Early Access ****, I wont be buying Black Mesa until it REALLY wows me.

Well that is true. They did broke a lot of release promises and it's still is buggy but it's an early release but as you said, you never really care and you're also right about it becoming paid all of the sudden. I just got excited and bought the game. The only difference is, there's multiplayer, a lot of different things in the game. But now I've realized, nothing really much changed well basically.

This mod is amazing! Feels like i'm playing a Valve's game, not a modification.
Now i understand what people felt like in 1998.

At first i made a really nice review to this game mod. But then i advanced further in the game and i got really pissed off... Yeah its pretty and scenic , yeah most of the voice acting is great and the music is fantastic but there is a huge annoying gash that just makes the game shit! AI: WHAT BASICALLY MAKES THE GAME SHIT AI: SHIIIT Soldiers...Im fine with other critters plaing running to eat you but soldiers(well the alien soldiers suck in this department as well). Anyway so where were we? oh…
