This is not the time, nor the place to discuss Surface Tension. The reason Black Mesa developers have this nearly impenetrable wall of silence when it comes to releasing details about the status of their work, is because people go mad with speculation with every small crumb of information they get.
This thread is a prime example. Go back to page 1, read what the developers actually wrote, then read everything that comes after it. Page 2 has some speculation about the announcement, page 3 has speculation about the speculation on page 2… heck, people nearly went rampant with ‘news’ that Black Mesa will be the first game released on the Source 2 engine (which itself hasn’t even been confirmed yet).
You guys are bickering over speculation about speculation regarding a speculative chapter in a to-be-released game. If you read carefully what developers have said regarding the inclusion of the extended Surface Tension in the past, you’ll find it basically boils down to “we don’t know, it could go either way”.
Now, experience tells us you’re not getting more out of the developers than that. So let’s just leave it at that and wait and see.
