Space Hulk: Deathwing releases next month and below you can find a video, showcasing 20 minutes of gameplay footage from it. This footage appears to be from the final version of the game (as all assets are in place).
Unfortunately, MyNameIsAleidan – who leaked this video – did not reveal the specs of the PC that was used. Still, this is PC gameplay footage (as indicated by the keyboard keys at the bottom right of the screen).
Space Hulk: Deathwing is powered by Unreal Engine 4, and aims to offer to players and up to three of their friends the chance to experience a desperate battle against Genestealers in the claustrophobic tunnels of a Space Hulk.
The game will support co-op gameplay, and will feature skills, new abilities, and new equipment that players will be able to upgrade.
