Soul of the Ultimate Nation Classic is a free to play fantasy hack & slash MMORPG for PC (Windows) by South Korea studio and publisher Webzen Inc., and a reboot of 2007 MMORPG SUN Online which closed on July 3, 2013. Changes brought with SUN Classic include a few graphic improvements (but not that many, keeping the game compatible with older or low-end PCs) in the form of added shadow effects to objects (which were non-existent then), adjustments to the coloring to emphasise visual details and change the feel of some of the biomes, spell animation improvements and more, as well as gameplay system improvements such as more ways to loot and progress characters, accessibility improvements including an optional auto-combat mode, UI overhaul and more.
