The Mercenary suit is an armour featured in S.T.A.L.K.E.R.: Lost Alpha.

Stalker suit from the Merc faction. Its design is based on the suit used by the special forces of the Western armies. Due to a special treatment of the fabric, the armor has a strengthened stability during the physical movement of its plates. Its protective properties are slightly better then those of the PSZ-7 military bulletproof suits.

  • Can be bought from Crash.
  • One piece can be found in Great Metal Factory. It is in the cargo space of the lorry, on the way to the Military Warehouses, but it is REALLY difficult to get there, because of an anomaly right next to the entrance.
  • Another piece can be found at the far end of the Swamps. In the remote room of the big building right after the bridge.
