Endless Crusade Previously, we have developed the Age of Heroes, a multiplayer VR combating game. The original Age of Heroes has multiple classes: mage, warlock, archer, priest. Age of Heroes also has 3 raids: Hall of Death, Freezing Stronghold, and Fort of Horror. Each raid contains battles and bosses that require different team cooperation and raid strategies. However, the game is not as interesting as we had hoped due to limited raids，lack of replayability and pricing problems. Thus, we decide to remake the game based on the lessons we learned from Age of Heroes.
