A map i made a while ago for the first Gears of War game on PC, Dont have a video because i cant load up this map any more sadly only have 4 screen shots.
Basically the map was 2 3 storey buildings down either side of a motorway road and in the middle was a church with much demolished and destroyed buildings and objects closing off the play area. All the vaulting and cover was set up and took ages to put in if i remember rightly.
