Media Release 2015


Hi there and welcome to this year's first and, oddly enough, singular update!
There's a lot to talk about, so let's get right to it:

First off, we'd very much like to apologize for the lack media releases on our part. While we did intend to focus more on the actual task at hand and spend less engery on presenting it, we didn't expect things to get so busy and found ourselves pushing our updates further and further.
As many of you may have noticed, our website is currently down. That's mainly due to technical and usability issues. We are however setting up a new forum and hope to interact more with you guys once that's up.

But, and this comes from the whole team: We are very thankful and touched to see so many of you being as excited as ever, hanging in there, showing your support and even boosting us into the top 100 on MOTY albeit having heard and seen nothing for almost 2 years. It really means a lot to us and it's a great reassurance that a lot of folks want this mod to exist as much as we do. A big thanks to all of you; keep being awesome!

Status Update

So, what's the status on Operation Black Mesa and Guard Duty?
They are both being worked on with full energy and equal priority.

Guard Duty is being developed as DLC / expansion for the bigger and more content-heavy Operation Black Mesa, so it won't require an extra greenlight campaign. So if you are especially interested in Guard Duty, be sure to check on Operation Black Mesa; we report on both mods side by side as they are very close together in terms of progress.

As a token of us being very much alive and kicking as ever (or early Christmas presents if you will), enjoy the rest of our previews:

Unpopular opinion inbound! I'd pay for that.
Surely consumers want everything free (and this whole paid mods hysteria only supports that), but I think that work should be compensated accordingly. There isn't much difference between mod and game these days, total conversions always were more of a game than a mod. It'd help development a lot more than donations, look how well Black Mesa does.

I paid for Black Mesa, then of course I would pay for Guard Duty in the same way that I would pay for Operation: Black Mesa. If it's good and done well, why not? Why not pay and value your work?

Will you be releasing a demo/beta like the BMS devs did? And if so will it be anytime soon?

There's a lot of comments going on at the OBM page so I'm asking here. In Opposing Force you get a lot of weapons early on. For example, you get the wrench at the beginning and then the knife less than 5 minutes afterwards. Will you be changing the spacing between getting weapons?

None of those games legally have "Source" after them. They are not made by or affiliated with Valve. Which is why the recently released Black Mesa is called Black Mesa and not Black Mesa Source.

So how about the mod titled "Jaykin Bacon: Source"? Why Valve didn't ask the mod's creator to rename it to simply "Jaykin Bacon"?

Black Mesa was *asked* by Valve to remove "Source" from the name so that the less knowledgeable wouldn't confuse it for being an official Valve installment.

No one's gonna think Jaykin Bacon is by Valve.

People still did confuse it though... I've never seen so many people yelling "WHY REMAKE GAMES AND NOT MAKE NEW ONES" and i just sit back and think, wow, what idiots
