Magicka: Wizard Wars

Magicka: Wizard Wars was a MOBA game set in the world of the Magicka franchise. While its core gameplay was 4v4 battles, the game had a heavy focus on the sandbox aspect. The game had no single campaign and was free-to-play. Servers were shut down in 2016 due to the lack of audience.
During arena battles, players controlled wizards who used elements to create spells. There were eight elements tied to keyboard buttons; every combination of three elements gave a certain effect on the wizard himself, his teammates or enemies. As the amount of combination was huge, their usage was limited only by players’ imagination. This mechanics was, in fact, a slightly reduced version from Magicka. As every element has an opposite one that counterattacks the spell, battles were based on the reaction rate of players.
There were three modes: a classic three-lane map with mobs and bases, a team deathmatch, and a 1v1 duel.
