It's a 2d strategy with customiseable armies (though limited) and cool titan units, the units come automatically as long as you have the mana, which is out of battle, you can choose where they move on the 2d map and you must research upgrades for them - Their Population Limits, the speed in which they are made, their HP and attack, also you get special abilities in which can help turn the tide of battle but only when upgraded they do such massive damage, there are 6 campaigns, which only completing them all will unlock all units, after you gain a certain level, there's also the Cave of Trial, which unlocks units like Titans from number 2 which take a large while to spawn and only have 1 population but are very powerful, but alot of mana costs, a back exit really speaking...
