The same is true in Guardians of Middle-earth. Teamwork is absolutely required in any MOBA game unless you want to get slaughtered. The goal is to work together as a team, destroy the enemy defenses and, ultimately, eliminate your opponent's base. Heroes are supported by low-level AI troops that are spawned at regular intervals.
Players are split into teams, with each player controlling an individual hero.
Although individual strategy can be complex, the overall concept of a MOBA game is relatively straightforward. For those unfamiliar with MOBA play, the genre was born from a Warcraft III mod called Defense of the Ancients.
