Enter the world of Epic, and experience an amazing adventure spanning a huge world filled with vast deserts, dark space stations, lush forests, and even Rabbit Temples.
Epic is a constantly growing game which has received wide applause for being an excellent blend of Zelda's action adventure game-play, Skyrim's RPG elements, and optional online 4-player Co-Op.
