This is my second go at a map, my first wasn't bad but It didn't work out. I'm going to try and submit this to the valve contest if I can finish it in time.
The map takes place in the sewers of city 17. There is a huge battle going on above ground, which can be seen and felt.
I plan to add a few traps and other ways to get hurt, there will be 'puzzles' that will give better wepons (like pulling wepons under fences or out of fires)
everything is working out well and I should have a finished product with in the week.
