Alarak is ya boy, joining co-op missions as the first field Commander with access to top-bar abilities. Alarak is an offensive hero with low survivability on his own, though he can sacrifice his own pawns to keep himself alive. He will always be the last unit to die.
You'll have to buy him if you want to try him out, however. Three new emoticons are included with Alarak’s purchase, presumably to sweeten the deal.
