Tomb Raider Sun Killer Challenge objective: Shoot five Sun Totems in the Research Base.
The Totems are very small and it’s hard to spot them.
Sun killer no.1
Once you reach the Research base go through the crack in the wall. The lightbulb will be in front of you, and the first totem is hanging from a beam behind the lightbulb.
Sun killer no.2
When you reach the first camp in the Research base, smash the door located slightly to the right. Look up and you will see the next sun totem.
Sun killer no.3
Look through the window and you will spot the next sun totem.
Sun killer no.4
At the bottom of the elevator shaft, look to the right and you will find the fourth sun totem.
Sun killer no.5
Proceed further and you will come across a wire fence. Look through the fence and you will see the last sun totem.
