Demigod is a DOTA (defence of the ancients, warcraft III mod) clone, but it does it with such style that you cannot help but love it. If you never played DOTA it is basically an RTS where you control just 1 unit/hero. Each team is split into teams of 2-5 players and each teams base is surrounded by towers, each 30-60 seconds a wave of AI controlled units gets spawned in your base and runs straight to the opponents base, there is a clash in the middle where waves of AI controlled units fight. Your job is to push the wave forward by killing the opponents waves of units so that your advances towards their base. You get XP and Gold if you are doing well and ofcourse there is some PvP killing as well.
