Eden Heroes is a custom World of Warcraft: Wrath of the Lich King 3.3.5 private server, launched as a passion project in November 2023. It combines progressive gameplay and familiar WOTLK atmosphere with features designed to offer new ways to explore the game. Players can choose among three modes: Hardcore, with a single life; Progressive, which advances through content from Vanilla to WOTLK by completing dungeons and raids; and Normal, where content is freely available.

The server supports any class and race combination, custom class spells and starting racial paths, automatic spell learning, and flight anywhere in Azeroth. Players can summon AI-controlled alternate characters to help with dungeons and raids, which are balanced for solo play or small groups. Other features include custom dungeons and items, pets for every class, up to five profession slots, and a Battle Royale mode. Eden Heroes also offers an in-game mall and account-wide systems for sharing items, gold, achievements, pets, and mounts across characters.
