I enjoyed this very much and it made me realize how much I miss playing long HL/OP mods.
This is one you will probably enjoy but it’s not very long, so don’t get too settled.

I tried it but it was to damn hard. There was no option for easy. Seems like you had to shoot a black ops/ninja more than usual. There also were a lot more attacking me. I had all the weapons at my disposal but was outnumbered.
When the game first started I got killed real quick,lol. When it started again,it start somewhere else.
I don’t know?
I’m gonna put it on the self for now,unless someone can get help me find a way to play on easy mode,

@Black Dog: Write skill 1 into console….
As for the map itself i played it through. It was nice playing an op4 map again. Still i woudn’t say that this map is a “play it now map”.
4 Stars from me and even that is to good for the map.
So if you’re looking for some quick action then try this map. Playtime is about 5-10 minutes it depends on your skills.

Forgot to add. When it restarted,I was in an a.c. duct in a underground parking garage. From there I took an elevator going down into a warehouse that was full of black ops. Then I got killed. A lot… lol
