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...
Confusing.
This is the word to describe this mod's maps layouts: every map require stumbling around, often withouth any real indication about where to go or what to do, especially when you have to backtrack, and you'll have to do that a lot.
The weapons reskins were okay, even if the sniper rifle were completely broken as it still fired bolts, didn't needed to be reloaded, and appeared on the left of the screen.
The voice acting wasn't good but it wasn't orrible either, and there were very few new lines.
The cutscenes were awful, completely out of touch with Half Life, and one of them was repeated around 6 times.
To top that you could still get damage while blocked by a cutscene.
The bonus map is not worth the trouble.
You never get to fight the enormous red strider featured in the intro.
The gameplay gets boring soon, walk around, spawn combines, kill combines, repeat for the entire game.
Long, but not good or fun.
