Peräjärvi is the main urban area in the game. When entering the urban area, you'll pass the built-up area signs, which means that the speed limit is 60 km/h. The urban area is located on the shore of the lake Peräjärvi so there's also a floating jetty for small boats.
The name Peräjärvi means faraway or remote lake, translated literally as end lake. Peräjärvi is also the name of the main lake in the game, in the fictional municipality of Alivieska. Alivieska is a result of the names of real towns Ylivieska and Alavieska in Finland combined. Vieska is a dialect word that tranlates to ford, a shallow part on a river that can be used for crossing.
There are a few notable buildings in the urban area, including a shop with fuel pumps and postal services, a wooden church with a graveyard which marks all permadeath mode deaths as gravestones, and a fenced off facility where sewage must be dumped to not get fined for illegal dumping. Behind the shop, there's an outhouse where you can save your progress. There's a running track on the east side of the village.
Pub Nappo is the main pub of the urban area and it's open from 8 pm to 2 am everyday.
There are eight houses in the urban area, two of them have septic tanks that can be emptied.
