AT 30,000 FEET... you are almost 6 miles (9.7 km's) above sea level. The human body is not made for these conditions. Temperatures can plummet to -60F (-51C), the brain is starved for oxygen and each step is a new experience in pure agony. It's difficult to breathe. It's difficult to think. It's difficult to move. And you still have to endure another 444 feet (0.14 km's) to get to the peak. So much for the good news.

STORYLINE: SURVIVE the SUMMIT ...The rebels are losing the battle against the strider onslaught that keeps growing. To help turn the tide of war you need to destroy the source of the Striders. That source is at the summit of what the rebels call, StriderMountain. There is only one way to get into the mountain geography and it's extremely dangerous terrain. The danger proves to be too much and you are forced way off target. Now, you must fight your way through the Combine Mountain Base Camp because it's the only entry to the mountain. As Gordon Freeman, you must survive the summit and destroy the source of the Striders.

Seems Strider Mountain is broken, again....

This is not caused by the mod, but as always by Valve who keeps updating there engine what corrupts the already excisting mods.

Should someone have problems with this mod then please let me know through
email or pm.

(I have to be honest and tell you that i can't look in to this myself now,
because i am very hard at work on my newest mod, see my mods list...)

The game seems to get stuck at one point that a rebel shimmies down a roof, and the game just sits there after the fact forever, any ideas or should I just try to bypass the area with noclip to just see the rest of the mod?

sorry for my late reply Guest, but i don't look here that often anymore because it is a old mod of mine. And i have made so many mods that it is hard to track all comments on them.
Am nearly done with my latest 18 sp-maps new mod, called Episode 3: The Closure.

to answer your question, my new mod starts were the original HL2 ep2 ended. that is also why it is called Ep3.
it will be released end next month.

It's slow and there are no clues to where the you have to go. Doors don't look like doors at times so you're just stuck trying to find the door while it looks like a fucking wall. And the sounds suck. Also it's trial and error a lot of the times and in the end it doesn't amuse me. The mapping is supposed to lead whereas in SM its just the map and you can go everywhere and you need to be in one little place. Making it look like a jungle and you need to find that one square meter in that jungle. The…
