SparkEdit is a tool that allows users to edit Halo maps. You can change, modify, add and delete objects on the map. It allows you to 'physically' move around the map and change stuff in real time. It is designed for Microsoft Windows. Interestingly, the icon of the program file is of 343 Guilty Spark. This also gives the program its name.
