Atomgrad EP. 01 Walkthrough

No.	Steps
1	At the beginning of the mission, you will be asked to locate the Echo Team by opening the submarine doors. Prepare first by equipping armor before heading out.
2	Clear out enemy hostiles in the tunnels. NOTE: Move cautiously as there will be claymores situated in corners.
3	Avoid enemy contact by diving underwater. You can also make your way to the second floor to gain a better view of the area.
4	Refill you weapon ammo, equipment, and plates through restock crates. You can also loot up dead soldiers to recover some resources.
5	Make you way to the control room and use the CCTV cameras to find the codes. You can find them on the Control Room A2 Sec. 5 and Control Room B2 Sec. 10.
6	After opening the submarine doors, get the oxygen tank found on the left side of the tunnel.
7	Submerge underwater and swim through the gap found in the wall. This hole can be found in front of the red light.
8	Swap out the air tank among your squadmates to maintain your oxygen levels and avoid drowning.
9	Swim until you reach the stairs. There's only one path here so it should not cause you to get lost.
10	Equip the P890's found on the upper floor before heading to the red light found at the bottom floor. These will be used to shoot the trip mines.
11	Swim to the left where you will find a door at the end of the hallway.
12	Pass through the door besides an elevator with Trap Wires. It will get you to the hole will have green lights marking it, and swimming through it will lead you to the safe area.
13	Make your way down and swim through the debris while following the yellow markers. You will then find the second control room on the left side.
14	Open the generator and make your way through the doors one by one to reach the second safe area. There will be times that the switch won't work after using it once or twice. You can fix that by restarting to the last checkpoint and it will spawn you on the next area.
15	Clear out enemies in the armory. There will be a juggernaut at the far right of the hallway so make sure you have armor plates equipped. NOTE: There will be a second juggernaut at the left side of the hallway.
16	Find the room lit by a green light and make your way past the vents. Make your way to the flooded tunnels and shoot down the bomb drone near the armory.
17	Keep following the red marker where you will eventually reach a hallway. Eliminate the enemy hostiles and reach the control room where you can activate a console.
18	Coordinate with your squadmates to enter the codes. NOTE: Cyphers will only be displayed for a limited time so make sure to catch them all before the timer on the third Cypher runs out.
19	You will be engaged by enemy hostiles as well as bomb drones during this sequence. Make sure to equip armor plates and have sufficient ammo to fend them off.
20	Wait for the Keypad Blast Doors to be unlocked. Hold your ground as enemy reinforcements engage you. NOTE: You and your squadmates will have to wait for four minutes for the door to unlock.
21	Regroup with your squadmates at the Blast Doors. Watch the cutscene and that will be the end of the Raid.

How to Solve Atomgrad EP. 01 Raid Puzzles

First Sequence Code

No.	Step
1	The puzzle requires you to enter a passcode based on the American and Russian letters displayed on the Red Terminal found at the corner of the room.
2	Use the CCTV Station to navigate to the cameras of Control Room A2 Sec. 5 and Control Room B2 Sec. 10 where you'll find the letters paired with their corresponding code number.
3	There will be two CCTV stations. One beside the passcode terminal and the other one will be located in the room next to the one you're currently in.
4	You will have to enter three different codes. Two party members will have to man the CCTV Stations while the third member will enter the codes. NOTE: Each member will have to take turns in entering the passcode as the previous person who entered the correct code will be locked out of the terminal.
5	Take note of the letters shown on the Red Terminal. These will be the letters that the CCTV members will have to look for and relay the information back to the person entering the codes.
6	FIRST CODE: Three letters will be displayed on the terminal for the first set of codes. Input the correct deciphered number on the passcode terminal starting from left to right.
7	SECOND CODE: Four letters will be displayed - one of them is a decoy in order to confuse you and will not be shown on the CCTV. If a letter is confirmed to be fake, ignore and skip to the next letter code to decipher.
8	THIRD CODE: Five letters will be displayed with two decoys. Again, ignore and skip the fake codes.

Second Sequence Code

No.	Step
1	Activate the Blue Room Control Panel and leave one member stationed in this area as the first set of letter codes will be displayed here.
2	Same as the previous step, activate the Red Room Control Panel and have one member handle this room.
3	Third member should head to the passcode terminal which will be located at the middle of this sector and will have the responsibility of entering the codes.
4	The person in charge of entering the codes will have to call out the letters displayed on the terminal to the other two team members.
5	Blue and Red room members will have to respond quickly with the correct number codes back to their teammate entering the codes.
6	Once all codes have been correctly entered, the Blast Doors will slowly open and you'll have to defend the area against waves of enemies.

Second Sequence Codes Have A Time Limit

The Second Sequence Codes will require your team to enter the codes within a given time frame, otherwise the letters will change to a different one and your team will have to enter the passcode all over again once the timer runs out.

• First Code: 60 Seconds
• Second Code: 40 Seconds
• Third Code: 30 Seconds

Bomb Drones and Enemy Soldiers Will Continously Spawn

Red Room and Blue Room members will have to keep an eye out for Bomb Drones and Enemy Soldiers as they will constantly spawn and attack them.
