Pochinki is a large city that is around the center of the map. This is one of greatest places in the map to loot, since it contains many large buildings and it is really tight close quarters combat. However, lots of players know this, which means there will almost certainly be many landing around this city looking for the same things you're looking for. This means that landing here is a high-risk, high-reward situation.
Pochinki is basically dead-center in the map if the flight path goes right across it, you could expect to see 20+ players landing here. The loot in Pochinki is basically as good as school’s loot, you should expect to come out of Pochinki with level 2 gear, ARs, DMRs or SMGs. There are two things that can happen when you land at Pochinki rather that you get a twelve plus kill match or you die right away. This is why many people are afraid to land at Pochinki as they don’t want to die really fast and lose a ton of points.
In real life, Pochinki is a small village in the Mordovia region in Russia. It's about 200 km (124 miles) west of Ulyanovsk and 700 km (435 miles) east of Moscow.
