Lego City: Volcano Explorers is a 3D driving game in which the player explores a lava mountain to find rocks for research purposes. The roads are very rocky and there are obstacles such as randomly falling rocks and volcanic gas. Look for a blue area to pick your rock and send it back to the truck. There are 3 different vehicles that you can play with. Unlock them one by one. Collect as many studs in the map and don't get hit by rock or gas, or some of your studs will be dropped. Have fun!
