DESTROY 5 SUN TOTEMS
1: When you enter the research station and begin to hop down the platforms, there will be a light bulb hanging in front of you. The first totem will be to the left of the light bulb, against the wall.
2: When you reach the camp in the research station, look through the open door on the right side. Look up and to the left and you will see the totem on the wall there.
3: At the same door as the previous totem, look directly across the hall and you will see a body hanging through a window. The body will have another totem on it to shoot.
4: When you reach the bottom of the elevator shaft, look through the fence to the right before continuing through the next corridor and you will see the totem on the wall there.
5: After you pass the elevator on the bottom level, continue to the corridor and there will be a fenced-in area on the right side. Look in this area to the right and the totem will be hanging there.
