Infinimine

"Infinimine is a simulation game that allows 2-player co-op, or massively multiplayer interaction in a mining setting. The game offers four advanced classes, each with unique skills and buffs, and encourages players to team up with others to speed progression and access guild-related bonuses. Collect and upgrade pickaxes and lanterns, and gather 120 unique ore types, some of which provide recipes for additional upgrades."
