In order for a wound to heal, it needs air, protection from further harm and space from the elements. With time, the open sore will scar over, a hardened reminder of past pain. But if the wound is constantly irritated, given no room to breathe, it will fester. The bloody gash caused by centuries of warfare between the Vektans and the Helghast has never fully healed. Three decades ago, the home world of the Helghast was destroyed and they were forced to flee to Vekta and share the planet with their bitter rivals. Now the constant exposure and incessant clashes between the two races have turned the wound of ancient conflict into a festering cold war. Only a great wall and the efforts of the ISA stand between the two sides ~ that, and the ever-vigilant efforts of Shadow Marshals like Lucas Kellen. In a steadily deteriorating world teetering on the brink of total destruction, peace is the only chance for survival. Tread lightly, however. Every choice you make will either lead the world closer to healing ~ or nearer to death.Don the role of Shadow Marshal Lucas Kellen, who spends his days fighting the constant discord that threatens to unravel into all-out war. When a mission brings you face-to-face with the deadly, mysterious female Helghast solider Echo, an entirely new side to the ancient conflict is uncovered, and you'll have no choice but to face the truth and decide what kind of hero you truly are. Harness the expansive arsenal of futuristic weaponry and gadgetry available to you as an elite operative of the ISA. The commandable combat drone, OWL, functions as an extension of you to augment your abilities to a jaw-dropping degree and deliver a host of innovative tactical options.
