S.T.A.L.K.E.R. 2 - Heart of Chornobyl

I take my 7th load of loot from the south, up to Zalissya. With plenty of daylight left, I decide to take a quick trip to Pol Depot. I meet the usual Bandits but then a storm blows in, and I get trapped by Boars on the roof of an oil tank, in the middle of a thunderstorm. I decide to get some practice throwing grenades. That is something I need to improve my aim with.
