Very good mod, I've loved the old beta and now in Source 2007 engine!!! the remake of the e3_terminal is good, but in all the new maps (e3_terminal, the rooftops, and anything what was not in 1.4) has the "source-cannot-find-skybox" effect, that blurry ****... so please if you can repair this! and on e3_terminal, the cops who are terrorizing citizens at the APC, has a very funny head from a distance...
But very good!!! VERYVERY GOOD!

Whats wrong with this. I try to start it, and steam says "cannot start in offline mode". My area does not support high speed anything. I'm currently getting 28.8k and thats way better then it has been for the past month. I thought the mod was a stand alone. My steam computer is not where I download from.

uhh, well sometimes if you don't have a steam connection it won't read you as loged on, and it will read your games as un-installed. but yeah, your right..stand-alone games, like half life2 shouldn't be affected...

Oh yeah, found the Mod yesterday, and I already like it. It's the best Mod i've played so far. I watched so many Videos of Half-Life2 Beta and MI-Mod. The old Stalekr word perfectly, but there are some ragdoll-problems. For example one leg always disappears into the ground.
Oh, and another Problem with the map where the hydra is (e3_under_02):
When the Hydra attacks, the animations become laggy (the attack of the Hydra is more like a clip-show).

Sure you're using a legal copy of Half-Life 2? These problems only occur on cracked copies of Half-Life 2.
