Click Here for the zip. I changed a few things. You may or may not like all of the changes. Let me know what you think. You do not need to rename or move the old HeH level. To play the new one, look for dm_hangemhigh or br_hangemhigh in the game menu. I'm sure hika will add this to his test server when he sees this.
BTW, performance is pretty bad if you run this in the mod version of wq3. But thanks to hika's enhancements to the SA it runs just fine for me in the stand alone.
However, I'm keen to know if anyone experiences bad frame rates. If it's too bad, removing the texture blending should fix it.
