Platformines is a platform-jumper shooter that takes place in a mine (who would have guessed?) It was released by Magiko Games in March 2014.
The basic premise is that you are a member of a crew that mans an underground excavation vehicle called the Robodig. It has broken mid-dig and scattered the nine block cannons that could be used to repair it. The mines are filled with hostile monsters of various shapes as well as hostile weapon-toting humans. At any given time the location of the next block cannon is marked on your map as well as providing a directional arrow and distance on the main play screen. So you have to navigate through the maze-like mines fighting hostiles all the while to get to each cannon until you’ve collected all nine.
