Escape was the injury. Relapse was triage. Now… it’s time for the surgery. The Outlast Trials introduces the Invasion Experimental Therapy, which was announced today at IGN Fan Fest with a gruesome new trailer illustrating the new, PvP Invasion Mode. The centrepiece of the upcoming major update in Season 4, Invasion Mode will  allow players to enter the Trials of their fellow Reagents, disguising themselves as Imposters and wielding brutally effective knives to sabotage and slay their opponents. Combining unique co-op strategy with close-quarters combat, the new Invasion mode heightens the suspense—and the violence—of The Outlast Trials on October 21st, just in time for Halloween.

You are not your brother’s keepers: you are your father’s children. And a father gains the trust of his children by trusting them himself. That’s why the ever-gracious Easterman has provided his beloved children with the tools they need to truly sympathize with one another: knives, security cameras, and disguises made of human flesh. After all, sometimes you have to hurt the ones you love to help them get better… and in the world of The Outlast Trials, harm and healing always go hand-in-hand.

Accessed via the Sleep Room Terminals, the new Invasion Mode allows players to join as either a Reagent or an Imposter. Only a limited number of Imposters can invade any given Trial, but while the others wait, they can be the eyes and ears of their murderous teammates. Each Imposter will get a chance to invade the Trial, as their peers succeed in their sabotage…or die trying. 

Key Features of New PvP Invasion Mode:

• Become the Hunter — Stalk your prey from the shadows, utilizing stealth and subterfuge to sneak up on unsuspecting Reagents before going in for the kill. 
• Surveil the Trials — Plan your route and attack strategy by carefully considering surveillance camera footage. Your fellow Imposters 
• Don a Deadly Disguise — Dress yourself in the garb and skin of your targets to gain their trust. Then, when the moment’s right…
• Stab Them In the Back — Close-quarters combat is the only rule of engagement. Outwit your opponent with multiple blade strikes or a single, lethal stab attack. One slip up means certain death, ratcheting up the intensity in the high-pressure Trial arenas.
