PIONER is a first-person MMO shooter from GFA Games, a Russian studio headquartered in Serbia; it entered Early Access on 16 December 2025. It is set in an alternate Soviet past on Tartarus, an island hit by a man-made anomaly and left with abandoned buildings, monsters, rival factions and artifacts.
The map covers more than 50 square kilometres before counting dungeons. There is a story campaign plus faction missions, where loyalty unlocks rewards and extra storylines. Characters have no levels or classic health bar; gear and realism matter more. PvP is confined to dangerous zones called the Shadowlands, while most of the world is PvE.
It suits fans of S.T.A.L.K.E.R.-style atmosphere who want it online. It is still Early Access, and recent reviews complain about crashes, high ping and damage balance.
