Harpstone was constructed in 2143 and entered the AGL a year later. Running alongside the buildings of Omnicom's Communication Centre in Greenland, the Harpstone circuit keeps the local workforce entertained all year.
First featured in version 0.3, Harpstone started out as a small Figure-Eight track with an overpass. Back then set at a relay station on near the south pole it was surrounded by tall icey cliffs and huge white towers.
A playable build of this version of Harpstone is available on the Steam Workshop.
Version 0.5's iteration of Harpstone is unique in the sense that it had 2 different layouts with varying difficulty in the same build of the game.The easy layout passes through an icy cave and features longwinded tilted turns, while the hard layout has a miriad of chicanes, rapid height changes and a long S-Turn. It's scenery still consists of ice cliffs but now also features tall high voltage pilons towering above the entire track.
0.6 and 0.9's version of Harpstone use the same layout as the current version. 0.6 relocates the track to greenland, the scenery is far more open than the older ones and features vast ice-scapes and a giant building complex. The 0.9 update only featured minor scenery updates, updates to the texture atlas, lighting changes and a rebranding of Omnicom.
