I got a job from Sidorovich to clear out some Zombified Stalkers, that were along the railroad tracks, east of the railroad bridge. I had intended to check out the dead bodies on top of the railroad bridge, so I went there first and then took the loot from the four dead bodies, back to the Rookie Village.
I departed once again, in bad weather with rain and low visibility, taking the same path to the north, coming to the railroad tracks and then going down the hill, across the road and back up the embankment. I saw a Duty squad I talked to briefly and was soon back on the railroad tracks going east. I came upon the Zombies, there were about seven of them or so. I had to shoot them many times. A few that fell got back up. I went to go loot them and returned to the Rookie Village the same way. Later I hit the I.P.S.F. Outpost, kill three soldiers and went in the main buildings and barracks, looking for any loot I missed.
Game Note: One of the recent patches, I think 1.5, made it so every dead body you had looted before from the game start, now has new loot on them, as if you never looted them the first time. For that reason, I revisited the dead bodies on top of the Cordon railroad bridge, that I had to jump into the Bubble anomaly to teleport to the top.
