It's a top down TBS that plays really well. You control a group of mercenaries that take on various job to earn cash to upgrade their equipment.
There is a 6 scenario single player campaign that's not too easy.
There's also a kind of random play. Each day 3 missions are online for you to try and earn cash. They change every day and vary. Some are clear a compound, escort important person, guard areas, etc.

Nice tactical squad game.
