Fight computer units similar to the style in Impossible Scenarios (a custom map from SC1) and gain minerals and gas to buy items or research stronger abilities. Each hero has 9 abilities of which 5 needs to be unlocked by research. There are 6 types of heros, each requiring unique gameplay as they are technically roles, from all-around unit, spellcaster, support, etc. Of course, you must defeat opposing human players you encounter. The map is essentially a maze with big corridors for PvP combat. Heros can also equip some of the items as abilities in addition to the 9 abilities they have. There are special areas that contain a tough computer enemy or enemies and they give out rare and strong items. Found in NA server.
