Engineer Smurf is part of the train and rail system in the mountains. His hut is available for 30 Smurfberries from the build menu and works as a train station.
His hut gives out 500 XP daily and if at least one of the other Train Stations has been bought it also gives resources daily (see the table below for more information).
The rail system works similar to the path tiles and the Space Rivers. In the build menu category “Train items” there are several rail tiles available for purchase. Read More→
