Increbiblely Simple, which is some times needed in death matches, however. Little tips to help.
One, this is no man's land, front of battle. Yea sure, I can imgaine cows grazing here. Put up smokeing craters and hide grass in corners where not much battle happens.
Two, more props, in battle there are thousands of little things, burnt trees, bunkers, caves, trenches etc... this adding of props can help with the 'warfield' look.
Three, though extremely practical, the maps does not hold enough detail. Excample those ramps just don't work.
Four, Houses, duplicated and undamaged.
Five, spice up your build with emitters and lights. (Maybe Events unsure)
Other wise I like where your going, (Not where your at) with deathmatch builds. Maybe next time make a capture the flag, or siege TDM.
Enjoy yourself building.
