This is a FPS Capture the Flag map in Unreal Tournamnent.

Capture the Flag works differently as opposed to regular Unreal Tournament Captue The Flag round maps. In this map, there  are 4 Red, 4 Green & 1 white flag. 

These flags are placed in center of the map. Each player collects a flag for his respective team. Doing so gives a point to that team. 

If a player manages to get its enemy's flag to his base, then that team recieves double the point of what that flag's worth is.

White flag is a special flag which yields five times more than the regular flag. 

I have used Unreal Engine's Unreal Tournament Level Editor to create this map.
