Chapter V: Crack in the World | Walkthrough The Bureau Guide
Last update: 11 May 2016
When the mission begin, move forward going through the next floors of the dam. When you enter the first building (with a moonwalker at pumps) turn left and read the note left there. Then, go downstairs using the staircase and stop at the dying moonwalker. A man will vomit, releasing the Silacoid which will attack Carter. Kill an alien and enter the room on right: you find there another document. When you read it, exit the building (notice some conventional ammo and weapons in here).
When you get to the next part of the building, you'll see a cut scene. When it ends, deal with two Outsiders, one Elite Outsider and one Psion Commander. The last target is the most problematic, as he can clone himself. After all, it's better to finish off weaker enemies at the beginning, what decreases enemy fire power. When the reinforcements arrive (Outsiders and their Elite versions), kill them as you like. If you didn't kill a Psion Commander yet, he'll run to the further part of the building. Collect ammo (chests on right) and move forward.
Here, a little more difficult task awaits. You'll run into a group of Outsiders and Elite Outsiders, who have good position. After a while a huge Gunship with additional Outsiders appear. Don't hurry with eliminating the flying machine - every time its HP decreases significantly, it drops a troop of enemies (it has two such groups on board). So focus on the infantry and then on the plane. If you run out of ammo, look into the room on right (you have to go upstairs).
After the fight, enter the next room and use Resupply Station. In the next room you find an alien Scout who will quickly disappear (no time to harm him). Look for collectibles in this room, you'll find three of them: Recording, note and photo. Move forward, you run into a Scout once again. Don't fight him, just duck behind a cover and wait. When he disappears, move forward and read another note from the shed in front of you. Then return to the corridor and kill an Outsider coming out from the corner. Move the squad into the room from which he emerged.
After a short walk you get to the great chamber with three alien devices. Approach the first one and turn it off with a switch. When you get on the bridge leading to the next machine, two Scouts, two Elite Outsiders and single Elite Phantom will appear in front of you. Deal with the first ones at the beginning: they are tough but they also deal a lot of damage. An optimal way to do so is to use Lift and firing at them. You can also make use of summoned allies (Silacoid and Drone), because enemies have impressing fire power. You can also bombard your targets or set up XCOM Turrets.
Enter the room from which enemies emerged and collect ammo from there. When you move forward, you'll be attacked by Elite Outsider, three Elite Phantoms, Scout and a Minion Commander. Kill the latter one first, as he can summon Drones and Silacoids. Lift him and fire down, eliminating the remaining enemies in random order (use area of effect abilities and grenades). If Carter has a Mind Control use it against a Scout to get the best output.
When you approach the third alien device, a Muton, Scout and Shield Commander teleport next to you. Ignore the Muton for the time being as the rest of enemies is much more dangerous. Don't let the Commander shield his allies (Lift him, Taunt him or just kill him) and then eliminate dangerous Scout. Lonely Muton shouldn't be a problem. When it's done, pick up a schematics Laser Efficiency Pack from the shelve on right (increases the clip size in laser weapons) and turn off the alien device.
When you turn off the last device, enter the room in front of you. In this moment you'll be attacked by Elite Phantom, Scout and Minion Commander (after a while two more aliens will appear). Neutralize the Commander and then his fellows. Then enter the room and listen to the Recording on its right side. If you run out of ammo, enter the roof and use weapons from there. After that, push the button ultimately disabling all alien machines and go through the opened gate.
When you get into the corridor, turn right and enter the room moonwalker sitting at the table. Under the wall you find another note you can read. In this moment you'll hear a man screaming in the other room - you won't be able to safe him and run into a group of Silacoids. When you kill them, return to the corridor and go downstairs.
After a short walk you get into room with three Outsiders. Eliminate them and go downstairs. On the computer in the middle you find a Recording to listen to. Then, go through the door and use Resupply Station. Enter the big, flooded hall and move forward eliminating more Silacoids. Notice also, that in one of passage room you find another Recording. Don't forget listening to it. Before you get into a tunnel, look also at the middle part of the hall and collect a schematics Anti-Personel Pack (increases damage dealt to enemy without an armor).
Go through the breach in the wall to the next part of the building. For a some time you walk without any attention from enemies, but finally you run into several Outsiders. Kill them and enter the room on left - an alien arsenal all for you. Then go forward and when you meet more Outsiders, defeat them and collect ammo. Open the gate and head for an Avenger. When you get close to it, it turns out that the gates to alien planet are closed. So you have to go to the Command Center and deal with this problem.
Prepare for meeting Elite Outsider, two Elite Phantoms and an Advanced Drone when you get to the place. Eliminate the latter one at the beginning, because he can Lift your squad members. Then kill off remaining aliens in random order. When it's done, approach the main console and launch it (you can also collect nearby ammo). Prepare for a heavy fight!
When enemies appear, kill the Drone first. Then take control over one of two Elite Outsiders (if Carter has a proper ability) and then Lift Minion Commander and fire it down. It's only a beginning. After a while Elite Phantoms and more of Elite Outsiders appear. Approach chest on left and pick up Plasma Assault Cannon, which is one of the best weapons in the game. If you run out of ammo, ammo box can be found in the same chest and behind you, on the console. In the further part of battle use new weapons and all abilities; especially the area ones will be useful on the left side of footbridge (from where enemies are coming).
Head for Avenger and stop at the computer - there you find an Endurance Pack, which increases maximum HP and makes the healed character regenerate with additional HP. When you pick it up, enter the flying saucer and watch a cut scene. In a moment you'll be taken to the alien planet!
When you land, approach the Resupply Station and use it. In the next room, you'll have a difficult but schematic battle. When you launch the panel in the middle of the room, a huge Elite Muton appears. When you take him one third of his HP, he runs away and summons several Elite Outsiders and Phantoms (don't care about transporting them Gunship). When they're killed, boss will return to the battlefield, jumping on the podium on left. Scheme will repeat: when you deal proper amount of damage to hum, he runs away and summon reinforcements (the same like previously but more numerous).
Third encounter is decisive. Muton jumps on the platform on right supported by the another group of enemies, this time with Minion Commander. Kill the Commander first, then the infantrymen and then focus on the boss. Change position and pick up ammo during this battle - you find a lot of useful things in nearby buildings. Use all abilities and don't fear to fall back: sometimes it may help you win.
When the battle ends, approach the console and turn right - on the box you'll find Kinetic Acceleration Pack, increasing damage dealt to the enemies without shields. Then launch the mechanism and watch a cut scene. When you capture the mysterious "demon", you can go back to your base.
