Moi Rai Games have released Forgotten World, a big free DLC pack for their creature catcher RPG Monster Sanctuary.

The highlight of Monster Sanctuary‘s Forgotten World DLC is the titular new region. This new area is meant to be explored late in the game, and contains 9 of the DLC’s 10 new monsters.

Other new additions include new weapons and accessories, new skill nodes for every skill tree in the game, the new Ancient monster type, new exploration abilities, new hidden rooms and chests, and a new super-secret Champion fight that the devs say is the hardest battle in the entire game. There are also new ways to play Monster Sanctuary in the form of the Randomizer, Bravery, and Permadeath campaign modifiers.

You can find a launch trailer for the new DLC below.
