Start an online game in Poisson. Near the barn, next to one of the truck respawns, there is a flaming building. Get on the second floor by climbing the stairs, then turn around and you will see a small side room. Go in the room. The wall is partially destroyed and on fire. Notice that on the wall you can climb to the third floor. Slowly and carefully get on the edge of the second floor and jump up on the wall, jump again, then once again. You can now access the third floor of the flaming building and can walk through the roof, giving you a good view of the area around the fountain.
