Fire in the Sky

Get Rocket Parts and Detonator: First things first, head to the waypoint. You'll need to collect three rocket parts scattered around the area. Once you've got those, grab the detonator. It's pretty straightforward, just follow the markers on your map.

Head to Tazendeer Ruins and Old Base: After you've got your initial supplies, it's time to move on. Teleport over to Tazendeer Ruins and then make your way to the waypoint that leads you to the Old Base.

Clear Maliwan and Find Typhon ECHO Logs: Once you arrive at the Old Base, you'll need to clear out all the Maliwan enemies hanging around. After the area is secure, you'll be on the hunt for three Typhon ECHO Logs. The first one will be dropped by the last Maliwan enemy you defeat in the camp – make sure to grab it! Then, head towards the next waypoint. You'll go through a tunnel and reach a dead end with a scaffold. Shoot the ECHO Log off the top of it to collect it. For the final ECHO Log, head to its waypoint. You'll encounter a boss named Omega Mantacore. It's not too tough, but be ready to dodge its acid balls. Once you've defeated it, collect the last ECHO Log from the ground.

Assemble Rocket and Place ECHO Logs: With all three Typhon ECHO Logs collected, head to the next waypoint. Here, you'll assemble the three rocket parts you found earlier. After a short wait, you'll need to place the three ECHO Logs into the rocket to proceed.

Place Detonator and Launch Rocket: Your next objective is to head to the final waypoint. Place the detonator down and then interact with it. This will launch the rocket into the sky, completing this part of the mission.

Talk to Sparrow: The last step is to head back to Desolation's Edge. Teleport there and speak with Sparrow one last time to officially complete the 'Fire in the Sky' mission.
