The Browning HPCS-1 is a unique weapon that was going to appear in S.T.A.L.K.E.R.: Clear Sky.
The only remains of this weapon are text files. It is an upgraded HPSS-1m. This weapon was going to have more reliability than the standard weapon. It was most likely created before GSC decided on adding the upgrade system.
