I would think so... If they're still working on it. However, from the screenshots, I think that it's safe to say they're working on it and this mod is very much alive.

It's dead now, with the SteamPipe update.
I had missing textures and models and maps EVERYWHERE.
Thanks a lot, Valve.

Allien Apr 2 2011, 3:57am says:

Very disappointed.
Long-awaited new version of MI.
And what I saw? Bugs! For example:
1) S15.radikal.ru
2) Not working fire extinguisher.
No doubt there will be more I have yet not seen much.

Course design borealis much better now, really liked the redesign of Odell and his animation.
But the gameplay has not changed practically. Nothing new or interesting. No new beta maps. Some changes rooftops, but the design is still very primitive. Where are the models of NPCs? Bullsquid, cremator, houndeye no models. Where hydra texture?
And you have done for so long :( I was expecting much more.

Make sure you have downloaded the Source SDK Base 2006 and 2007 in the Tools tab in Steam.

JCDenton2000 Jul 31 2013, 2:38pm replied:

I don't have EP2 or Portal/Portal 2 and it works fine for me. I have HL2/EP1 with the SDK bases though, so perhaps that's it.

You found 2 bugs... both of them arent near to being game breaking. Personaly i enjoyed the borealis chapter. You guys are expecting way to much from a mod.

Also, why is this download smaller than earlier updates?
Can it be added to previous files of 1.5.1 in order to have it without the bugs I experienced?

Good Q & I think the answer is no since when I added 1.6 onto 1.5 & started it up I got a fatal error window & its shutdown. right now i deleted my old MI & am installing just 1.6 by it self. Hopefully it works.

Mine crashes every single time I try and start it up. I get the box that says there was a problem with hl2.exe. I have the necessary games to run the mod and have tried restarting steam even uninstalling then re-installing the mod but it does the same thing. Other mods work fine so not sure what the problem is.
