Most chests can be found on patrol. Some only during certain strikes or missions which I will specify. Good luck and happy hunting Guardians. Cosmodrome... 1. Head to the divide(where you get the fallen walker event) from spawn. After you enter the very first building, the chest will be on a desk in the first hallway. 2. Head to forgotten shores. In the canyon on the way look for a cave on the left. The chest is in there and watched over by a dead ghost. 3. Continuing to the forgotten shores, go past the ramp that leads up towards the lunar complex and hug the left side of the cliff. Follow the cliff side out into the water. You'll see it around the corner. 4. From spawn, head up to skywatch. When you get to the room with the wizard, go into the next room and jump onto the roof of the room where the captain hangs out. 5. During the Sepkis prime strike, when you fight the boss, the chest is located below the platform on the right. Moon... 1. When you spawn, head left towards hell mouth. In the first clearing after you leave Archer's line is pile of rocks. Look there. 2. From spawn, go slighty right and up the hill and through the round building next to archers line. Enter the hive temple, and descend the spiral path to the bottom. Jump into the stream and follow it around. 3. Enter the temple of crota (we've woken the hive) when you get to the weird mechanical structure just jump onto the first little platform that leads into it and look down, there's platforms that staircase down the the wall that leads to a chest. 4. The world's grave... at the end of the mission when you face the final fight. When you enter the room, just walk off the platform and into the pool, turn around and look to the right. 5. When you fight Pholgoth, go down to the platform where the drop ship drops the enemies. Venus... 1. Go to the library from spawn, first chest is in the tunnel on the way behind a pillar. 2. During nexus strike (or patrol) go into the room where you fight the 3 servitors. On the right is room which now (if on patrol) has repeater shanks. The chest is behind a cubicle in the back of the room. 3. Go to campus 9 and look behind the building with the satellite dish. A scorch captain now stands in front of the building. 4. During the Archon priest strike(or patrol) while you're in the caves, after you kill the 2nd pair of hobgoblins (in the cavern with the captain)((immediately after the first hydra)) look up and above the crates and you can see the chest. Now just follow the path up and around to the level above. when you reach the tunnel with the exploding mushroom thing, just turn left and follow the ledge and eventually you can jump across to the chest. 5. During the Archon priest,( or patrol) when you reach the point where you have to deploy your ghost and fight minotaurs, harpies, and hydras, just run across the map to the fallen ketch, (big ship) the chest is on the right side at the front of the ship. Mars... 1. When you spawn for patrol, just go right and enter the first circular bunker. It's in plane sight on a crate. 2. From spawn, go left and into the tunnel. Before the end of the tunnel, there is a broken area of ceiling along the left side. Get up into the hole to find the chest. 3. Rockets Mc Dickface strike( or patrol). After you enter the first big room with the Psions, phalanx, collosus, and legionaries. If you go straight into the room and up the ramp, you should be staring at a giant blast door. The chest is above it, in the right corner. Use the blue pipes to get to it. 4.go into the basement where the vex are hanging out. Keep going to the train cars, jump over them turn right and hug the left wall. Theres a room along the way you can enter. Go inside, the chest is on the left behind a fence. 5. Go into the dust palace. Head down into the room where you have to scan/kill the phalanx during patrol missions. In this vicinty is another room with a desk and a window. The chest is behind the desk. If you go past it, before long you'll encounter 2 Psions doing god knows what in a hallway that leads up a staircase. Theres a window on the right as you climb the steps, the chest is through that window. Hope this helps you guys out.
