Play as a heroic Drill Keeper in this deckbuilding roguelike siege defense game where you travel the galaxy in an effort to secure vital resources for your people. As a dutiful symbol of the future, you will be tasked with protecting your Planetary Drill – build fortresses around your mining operations to protect it from the dangers that lurk in the depths of distant planets, designing labyrinthine pathways and traps to stall and bewilder the enemy. And if a sense of duty isn’t enough of a motivator, you should know that your parent corporation has installed a neural implant that will kill you should your Drill be destroyed – it’s expensive equipment, after all!
