Developer SureAI has confirmed that Enderal, the total conversion mod for The Elder Scrolls V: Skyrim, will arrive next month.

The mod promises a game that is set in its own world with its own landscape, lore and a dark, psychological storyline with what the developer calls believable characters. Like the original game, Enderal will offer an immersive open world with the added bonuses of an overhauled skill system, a housing system that allows players to design their own homes and refreshed gameplay mechanics.

SureAI, a small team of 14 based in Munich that is best known for its Oblivion mod Nehrim: At Fate’s Edge, claims to have poured 29,893 hours – nearly three and a half years of continuous work – into the project to date. That’s some serious dedication right there, folks. Players can expect anywhere from 30 to 100 hours of playtime, we’re told.

Best yet, the mod will be absolutely free for anyone that owns a legal copy of Skyrim, no DLCs necessary. The catch? It’ll initially be released in German with an English version slated to arrive several weeks later.

If you’re looking for something to hold you over until its arrival, you might want to check out the recent Holds The City Overhaul mod. As the name suggests, this 4GB mod overhauls the cities within Skyrim. Other favorites include the SkyUI, Climates of Tamriel and Convenient Horses mods, just to name a few.
