Stalker: Call of Pripyat → Skat-1 and Skat-4
Skat-1
Location: Jupiter Outskirts. We head to the helipad. The entrance is blocked by a minefield, but you can reach the helicopter along the fence. We approach, inspect, take the Black Box, and take it to Azot on Yanov. He says decryption could take about three hours, and it will cost a considerable amount of money. So, we wait three hours, then approach Azot. We give him three thousand and listen to the audio recording he received, which tells everyone to proceed to evacuation point B28 in the event of an emergency.
Skat-4
We enter the factory building through the southern gate and through underground corridors to a hall with a destroyed roof. The crashed helicopter will be hard to miss. We examine it, but find nothing of particular value. We need to find the Path to Pripyat .
