Опасайся демонов! — HotA 1.3.0+

Beware of Demons is a scouting adventure set in lands that no published map has charted, as its description puts it. The small 36 by 36 map is an underground level played at Impossible difficulty by three players, with only one human seat. Red (Inferno) and Orange (Necropolis) are computer-controlled, while Teal plays Cove, and the players form two teams. The terrain is mostly rock, dirt, snow and subterranean ground, with very little water. Victory requires surviving for a set number of days, and the game is lost when every town and hero is gone. Highlights include the Grail, powerful artifacts such as Titan's Thunder and the Sword of Hellfire, seven mines, and wandering stacks like a Power Lich and a Vampire Lord.
