Phantom Doctrine 2 explores an alternate reality where the Chernobyl accident was a deliberate terrorist act, and the first in a string of attacks orchestrated by a group called the Cabal.
You build a squad of agents with different skills then choose which one to send on each mission, where they’ll sneak in, impersonate enemies, use silenced weapons, and do whatever it takes to complete the job.
There’s also a tactical pause system and a return of the conspiracy corkboard as nods to the original game, but it does look and sound pretty different.
