I'll give you a hint, it's the same as regular 67thway_v14 :)

I actually didn't play yet that map

First button is at the barn house in the entrance to the tower.

Second button is in the room that is next to the basement entrance. Look for the door in the road.

Third button is in the pool.

Fourth button is in the barn area, all the way around on the other side of the wall.

Fifth button is on top of the barn. Once you've pressed the fourth, an invisible ladder will spawn on the side of the barn and you can climb it.
