Metro Redux Cheats for PS4

To get the Wheeler-Dealer achievement/trophy you need to exchange 500 Military-Grade 5.45 rounds at Exchange kiosks. In order to be able to do this you will need to get your hands on 500 Military Grade Ammo. This basically means you will need to continually buy shotgun shells and sell them back until you meet the requirement. The last opportunity you will have to unlock the Wheeler-Dealer achievement/trophy is in the Polis level. Remember to reload the checkpoint once you have unlocked the achievement/trophy to get all your ammunition back.

To get the Ka-Boom! Achievement/trophy you must explode 30 enemies. An easy way to get this is in the Outpost level by sneaking to the back right corner of the starting area and climbing the ladder. Quietly kill the two enemy guards you find at the top and then peer down to see 6 enemy soldiers gathered together. If you then throw either a sticky grenade or a regular grenade into the middle of them, and you should kill 6 of the enemy soldiers with one grenade. Now simply reload the checkpoint and repeat this until you meet the requirement of 30 enemies to unlock the Ka-Boom! Achievement/trophy.

To get the Pathoanatomist achievement/trophy you must kill 5 amoebas. You will be able to do this in the D6 level when you are alone with Miller and the pair of you spot some orange glowing globes on the wall which if you walk nearby to a creature called amoebas will appear out of them. To unlock the achievement/trophy you must shoot the glowing globes when the amoebas are out for it to count towards the requirement. All you need to do is walk by the glowing globes and shoot the amoebas as they come out. Any amoebas that Miller shoots though will not count, but this is not a problem as there are plenty of amoebas in the level.

To get the Ever Vigilant achievement/trophy you must disarm 10 traps. The easiest way to do this is at the end of the Facility level when you see a trap down a linear hallway. You will not be able to miss the hallway as you need to proceed down it for story progression, and you will also not be able to miss the trap as it will have lights all over it. In order to disarm the trap you need to approach it and press the X button on the PlayStation controller (A button on the Xbox controller). There is a checkpoint just before you enter the hallway so if you reload the last checkpoint and if you just repeat this 9 times you will be able to unlock the Ever Vigilant achievement/trophy.

To get the secret Savior achievement/trophy you must remove your gas mask when Lesnitsky demands it. This scene will take place at the end of the Contagion level when you find Lesnitsky holding Anna as a hostage. It is important that you DO NOT SOOT HIM but instead wait for him to start counting. If you take off your gas mask during the count you will start a cutscene and unlock the Savior achievement/trophy.
