INVASION EXPERIMENTAL THERAPY
The new Invasion Mode allows players to join as either a Reagent or an Imposter, but only a limited number of Imposters can invade any given Trial: while the others wait, they act as the 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. This new game mode is a lasting addition to The Outlast Trials, and a permanent fixture of its gameplay.
Observing invaders can ping their targets to help strategize and keep their fellow Imposters informed. Once an Imposter has spawned into the map, their objective is to identify the location of the Trial’s Reagents, sneak up on them, then bring them to a violent end, armed with nothing but their trusty knife. Knife attacks come in the Slash or Stab variety: the former quickly deals damage while the latter is an instant-kill that requires charge-up and close proximity to properly execute.

Imposters only have a limited time to take down their target. Once the time limit elapses, they must return to the nearest Insertion Gate or risk electrocution — and even death, resulting in a time penalty before their next respawn. But fear not, for Imposters are capable of seeing the noise and disturbances that Reagents cause, giving them an extra edge against their targets. At the end of the match, Imposters are evaluated based on the amount of damage inflicted on Reagents, as well as the number of slain Reagents and for staying alive through their turn. And lastly, Imposters are incapable of picking up Reagent items, but are uniquely immune to psychosis gas and Prime Asset effects.
