Damnation
Fact Sheet

PRODUCT DESCRIPTION:
Changing the landscape of shooters forever with a revolutionary blend of movement and combat in all three dimensions, Damnation is a non-stop test of reflexes, decision-making and action. Taking the shooter vertical, Damnation features massive streaming landscapes that set the stage for post-industrial battles between humanity and an unstoppable corporation in the wastelands known as Damnation. With the freedom to go anywhere and kill anyone to reach a goal, players create their own routes using vehicles, acrobatics and climbing to get around the huge maps.

In Damnation, players take control of Captain Hamilton Rourke, a member of the guerrilla resistance force known as the Peacekeepers. A veteran of the Great War, Rourke has his own personal agenda in avenging the death of his fiancé.

KEY FEATURES:
Huge Scale - With vast, streaming environments, Damnation’s levels are truly organic 3D spaces that cover miles of horizontal distance and thousands of vertical feet. Players choose from multiple paths and tactics in gigantic landscapes that unfold in all three dimensions. Using exhilarating combinations of swift, flowing movement and combat, players will be faced with frenetic all-action attacks that can come from any direction.

Player Choice and Freedom - It could take up to three hours in real-time travel to get from one end to the other and another three hours to climb to the top. But with acrobatics and vehicles, players are able to get their own routes, as they look at the massive map ahead, above and below them.

“Spirit Vision” - Players can activate the hero’s “Spirit Vision” power to see through walls and anticipate the enemy’s movements.

Daredevil Stunts – Players perform stunning moves at the limits of human ability to jump between ledges, swing on ropes and chains, and traverse vertical surfaces. Zip, slide, vault, shinny, swing and jump through the environment with intelligent AI attacking from all sides, above and below.

Multiplayer – Play through the entire singleplayer campaign in co-op or take it to the next level online with multiplayer. Experience action and tactics in vertical environments with fully enabled “Spirit Vision.”
