Build a squad of ultra-powerful heroes with synergized abilities and take on the difficult singleplayer campaign or go head to head against another player in online pvp.

You begin with an empty battle field and are provided a choice of heroes and upgrades to purchase from the shop.
Stacking multiple heroes of the same type lead them to level up.  Heroes of a higher level are much more powerful than their lower-level counterparts, so you must choose carefully if you want to invest deeply in a few heroes or try to overwhelm your opponent with quantity.
Upgrades function similarly to hero leveling.  Upgrades stack on any given hero, and more stacks of the upgrade leads to much more powerful effects.
Want an archer with wicked fast attack speed and poison arrows? You can do that! Or a Summoner that passes on his upgrades to his summons? That's possible too.
The upgrade system provides many synergies but you must be careful to counter your opponent's strategy.

In multiplayer, each game is different, as you are presented with a different combination of heroes and upgrades to pick from!
In Singleplayer, unlock new squads to take on the campaign with a new team composition and gain access to advanced difficulty levels as you progress!
