Corepunk has released some details on a new type of hero, the Mercenary.
Coming from a cold-hearted world of eternal winter, a mercenary is not used to feeling pity: it’s kill or be killed. Usually, mercenaries work as a trio: while a sniper takes out enemies from a distance, a berserker breaks through enemy ranks in a formidable onslaught, covered by heavy fire from an engineer’s turrets.
Mercenaries can take the form of snipers, engineer or berserker who each has a unique set of powers. See the full details in the official post.
