You can sell at the trader in the Cordon, to the scientist in the bunker at Yantar or to the Barkeep, and you can sprint (why are you walking? there's a sprint key) from anywhere in the game back to the bar in under ten minutes. In fact I reckon I could get from the stadium in Pripyat to the trader in the Cordon in under 15 minutes. As someone mentioned above you need to use stamina artifacts (2 will do), and to keep your weight under 50kg.It's good but very strange. Not to mention to get money you need to sell weapons etc but if you carry too many you get overloaded and walk like a slug. The only place you can sell weapons is to the 'trader' wh is always about 20 minutes walk away from where you are.....
Gets tedious fast.
Lots of potential but badly done.
