Individual heroes could be unlocked and persistently progressed by playing with them in one of many game modes including single-player campaigns, lane-pushing on various maps, and co-operative dungeon crawling.

Developed and marketed primarily in Asia. Players enter the match picking three heroes, and can swap which one is active after dying. In-game progression is heavily weighted towards loadouts, though heroes having a large choice of skills to level up, and lots of consumable items, also played a part.

Chinese game. Still seeking information.
