wtf your saying that i cant put eight guns on each side? cause thats bull**** if i cant.
You have 30 guns, 5 boxes of ammo, 13 co2s, 10 hoppers, and 10 barrels, all in a tiny part of your map 320x320 units. Per side.
Not to mention that you only have one spawn per side. All the entities were why you were overflowing, by the way.
Honestly, you need to texture your buildings better. Actually, just using more than one texture would be good. You need to re-align your ladder. You're missing a group of barrels on one side. The barrels are miscolored one the blue side. And you need to realign the barrel textures.
EDIT:
And I forgot he lights. That's not how you do lighting. You should use sky light (in the ArghRad readme) Or surfaces that emit light.
That's what's wrong with your map, apart from the layout.
