Played this for around 5 minutes and I have a couple things to give feedback on, Reasoning behind playing so little of this map are due to these problems.
1. The map is too big, I gave up looking for the last zombie. The map aint sectioned into little areas so the zombies just scatter around the whole map.
2. It's VERY dark, I can't see and I know I should turn my brightness up but I use this brightness for all other maps and it works well.
3. Big area, Little detail. You literally just put a bunch of walls and grass and finished. That's not cool in my books.
I also seen your room with all the guns on the wall...WHY?!! spread the guns out!, and as for the grenade wall...I ain't even going to waste my time explaining why there are around 15 grenade wall buys all in the same spot.
