Might and Magic: Clash of Heroes Preview, Trailer

GameSpot is next in line with a hands-on preview of Ubisoft's Might and Magic: Clash of Heroes, though they've also conjured up an official trailer to go along with it. From the article:
Clash of Heroes' turn-based strategy is played on both screens. Your army is presented on the bottom screen, and your opponent's army is on the top. Units are ordered into eight vertical rows, and you need to maximise their effectiveness by grouping similar units together. Vertically lining up three of the same unit type and colour will create an attack formation, whereas a horizontal row will result in a defensive wall that your forces can stand behind. Adding another three units to either formation will combine the two groups to make a more powerful one. The catch, however, is that you can only move units that are at the bottom of the screen, and you have a limited number of moves per turn.

While you have a limited number of units at your command, you can call in reinforcements to fill your population to its capacity. Our forces included elven archers, bears, pixies, deer, and dragons, whereas the enemy forces consisted of demons and evil knights. The type and colour of replacement units are random, making gameplay feel like a puzzle game at times. Deleting miscoloured units in between those of the same colour results in an attack formation, with the added bonus of giving you an extra move. You'll lose health if you unsuccessfully block an attack, but you can do the same to the enemy. You can also create link attacks by forming columns of the same colour and unit, which results in an attack bonus. The more links you create, the higher the attack bonus, and the wealth of tactics at your disposal means that there are plenty of different possibilities for battle.
