How to find an arena in Stalker 2 (Coliseum of Freedom)
Stalker 2: Heart of Chernobyl features an arena that is part of the Colosseum of Freedom quest, which includes gauntlet-style challenges and rewards.
In search of Whisp at the pig farm
The first task is to find Wispa, who usually hangs out on a pig farm in the Cardon region. After making your way to the farm, you'll encounter a group of ghouls trying to attack you. Try to take them all out at once and clear the area of all threats.
Once everything is clear, go inside the barn through the open door in the middle and you will find Whisp's body lying there to the right side. Loot his body to recover Wisp's PDA, which will contain information about a new merchant setting up shop in Cordon. This will also reveal the location of Wispa's hideout.
Sidorovich will now contact Skiff to inquire about the Wisp situation. After filling it, he orders Scyth to visit this new merchant and shut down his business before it even begins. Before heading into the tunnels to confront said merchant, be sure to visit the Wisp hideout along the way for a new High capacity AR416 Mag nozzle.
To save the traders or to kill them for Sidorovich?
Now head to the tunnels to check in with the merchants. here players will have two options about how to proceed in this situation. Either kill the traders outright to get your reward and thanks from Sidorovich, or take the ethical route and spare their lives but accept a lesser reward.
Murder of traders
Players can just go and start shooting traders without engaging in conversation. After killing the Swede and his peopleSidorovich will contact Skiff, thanking him for his work, and send some coupons.
Rescue traders
A second option is for players to holster their weapon before approaching the merchants in the tunnel start a conversation with your supervisorSwedish. Then you warn him about Sidorovich's attempt to drive them out of town or even kill them if they continue to do business in Cardona. Although the warning won't affect the Swede, he will still be grateful to Skif for informing him about Sidorovich and giving him the coupons.
However, as you exit the tunnel, you'll encounter Sidorovich's men, who will ask Skiff if he's going to go through with the plan to kill the merchant. You will have to fight these people to save the traders. After taking them out, the Swede will thank Skiff again for saving them and give him some more coupons. After this, Sidarovich will take his grudge against Skiff, but this choice will not affect your ability to use the Rookie Village facilities or experience trading with him.
However, you will lose the quest reward offered by Sidorovich.
