Battle having been and gone, your job, as a well trained dog, is to help in the process of demining in order for the land to be used. Sniff out the scent of explosives and show your handler where it is, the stand back and watch the humans do the heavy work. Levels would increase the number of mines and decrease the scent indicator, forcing the player to pay closer attention. Triggering a mine or failing to detect it would cause the level to restart. Cleared levels could develop overtime and be revisited to see changes. Changes could be influenced by the player, or minesweeper levels could be followed by sim-city like management of cleared land. The game could be potentially endless, but most likely would have a set number of levels. After completing the levels, developing the cleared land would give the player more to do. Players could chose between several dog breeds to play as, potentially serving as lives in that once used, a breed cannot be selected anymore.
