Rise of the Tomb Raider: Area 5A - Installation Vista, The Astronomer's Crypt - 100% Walkthrough

#riseofthetombraider #sovietinstallation #100%walkthrough #installationvista #theastronomerscrypt Sneak into the Old Soviet Base CLIFFSIDE ABOVE THE TRAIN YARD: After the cutscene, dig up a survival cache (1/21) buried near the wall to the north of the Installation Vista Base Camp. Then use the camp to make any skill and weapon upgrades you may have unlocked. At this point, you can begin to specialize in a particular skill set (Brawler, Hunter, Survivor) or spread your early skills out among the three sets. I tend to do the latter, so I usually choose either Eye for Detail (Survivor), Iron Hide or Dodge Counter (Brawler) for my next upgrade. You may or may not have the resources needed for weapon upgrades right now, but don't forget you can also upgrade your climbing axe. You'll be using it throughout the game, so those improvements will be very useful. Ride the zip line down into the canyon and dig up another survival cache (2/21) on the left side of the path just before the orange metal pole that anchors the line. There are birds and rabbits to hunt, as well as some trees you can strip for hardwood. If you need to get back up to the campsite before reaching the next fast-travel camp, there's a tall tree with broken branches you can use to reach a climbable wall and from there, climb back onto the ledge where you started. THE ASTRONOMER'S CRYPT: Continue down the path, but before you reach the corpse leaning against the stump, there's a wooden box sitting on a ledge on the right. Open the box for some supplies. Then squeeze through the crack in the stone wall into the hidden area beyond. At this point, your in-game map is updated, showing you've discovered the entrance to a crypt—one of many you'll encounter during your travels. Enter the CAVE ahead to initiate a Challenge: Into Darkness. The goal is to explore 5 caves scattered around the Soviet Installation. (This cave is marked C1 on the annotated level map.) Pick the 2 mushrooms on the ground ahead and collect 2 magnesite ore deposits, one on the right side of the cave, the other on the left near the bricked-up archway. Use your axe to break down the wall so you can get through the doorway into the cave beyond. Pick up 2 Byzantine coins in the next small chamber. The next contains a mural (1/12) inscribed in Greek. It is called Kokkos, the Astronomer and can be reviewed in the Crypt Murals section of the Documents screen. If you've discovered all the other Greek writings so far, this should increase your proficiency to Level 3 Greek as well as give XP. Continue along the tunnel until you can drop down to a lower level. Enter the cave on the left with the dripping water and icicles. Go around to the right and jump from the end of the ledge to the slightly higher ledge on the far side of the room. Mine some magnesite ore and then continue into the dark alcove to find a document (1/26), Kokkos, The Astronomer from the Crypts of the Founders series. Examine it for XP and Greek proficiency. Drop down into the centre of the cavern. Go through the small opening in the ice wall to find mushrooms, 2 Byzantine coins, and a container with cloth and another coin sitting on a ledge near a skeleton. Then return through the doorway in the ice and climb back onto the ledge on the right. Go through the archway into the main passage and continue downstairs to the left. Where the passage widens, go through the rough archway on the left and climb up three ledges to find 2 coins and hardwood. Turn around and use Survival Instinct to spot another container on the high ledge opposite. Jump across to get it. Then climb back down, return to the main passageway, and continue to the left to find the crypt proper. Along with the remains of Kokkos of Nicea, there are 2 piles of coins, one behind the sarcophagus, one to the left (4 coins in all). Open the sarcophagus to receive an ANCIENT BOW PART (1/4) plus 3,000 Expedition credits. When you find the other three parts of this bow, you'll be able to build it at any base camp. Return along the passage the way you came. When you reach the room with the broken ladder lying on the ground, scramble up the wall on the left and continue along the tunnel to the exit. Cross the open area and squeeze through the gap in the rocks to get back on the path. 🙏 Join this channel to get access to perks:    / @mrgamingzone   🎲 Twitch Channel::   / mrgamingzone   🐦Twitter::   / mrgamingzone   💰 Donations:: https://www.streamlabs.com/mrgamingzone
