[8.9]. Mission 9 - Skedar Ruins: Battle Shrine (2)

Identify temple targets: Move forward and kill the Skedar Monster to your right with the Falcon 2. Equip the R Tracker and use your radar to find obelisks (marked as yellow dots). Place a Target Tracer on each required obelisk. Navigate through the area, killing monsters, including a cloaked one. Find and target obelisks. Continue through openings, eliminating enemies, and follow the path to a fork. Take the right path to find another obelisk and place a target amplifier if needed. Return to the fork, take the first right, kill the monster, take another right, kill two more monsters, and collect their ammo. Take the right path to find another obelisk and place a target amplifier. Head towards the other stairs, turn right at the foot to find an opening with another obelisk. Kill the monsters and place a target amplifier if necessary. Completing this objective requires finding three obelisks.

Activate bridge: Leave the current area, go left, and run to a fork. Go right at the fork. Equip the Devastator and set it to Wall Hugger. Shoot a grenade at the wall behind the monster to your left. Cross the black bridge and go through the opening. If the bridge is missing, fall to the ledge below, turn around, kill the monster, and proceed until the ledges combine. Climb up the wall on the left. Run down the path and hop into the next area, killing any monsters. Go straight until the second left turn, facing a wall. Use the IR Scanner to identify the lighter red wall, indicating it can be destroyed. Use a grenade to blow it open and follow the tunnels. Drop down, go left, and enter the first door on the right. In this room, kill the small monster, then push the movable stone onto the light brown area to activate the bridge and complete the objective.

Enter Inner Sanctum: Cross the newly found bridge. Leave the room, go right, follow the path, and cross the bridge. Continue forward, equip the IR Scanner, and kill approaching monsters. Reach an area with a door to the left and a ramp to the right. Go up the ramp and through the door. Stay at the doorway and kill the two Rocket Launcher-wielding monsters below. Cross the bridge and kill the monster guarding the door. Drop off the right side of the bridge and find a Skedar cross to the left of a spinning pillar. Interact with the cross to be prompted to make a sacrifice. Push 'B' next to the cross to place your weapon on the ground, unlocking the door. Enter the door to complete the objective.

Assassinate Skedar leader: In the next room, defeat the Skedar Army, who emerge one by one from green capsules. After defeating them, proceed through the next door to face the final boss. To defeat the boss, shoot him until his shields turn green, then shoot the spikes behind him. He will eventually descend and chase you. Run away and kill any minions he summons. After destroying all but the center spike, use the Callisto's rapid fire to damage the large central spike. Successfully destroying it completes the mission and the game.
