List of mission 3 secrets
In chapter 3, you can find 9 secrets.
- Archives x3
- Costume x2
- Guardian Collectible x1
- Galactic Compendium x3
Remember to collect all the collectibles in chapter 3 in one go. You can't save progress while replaying chapters. This is especially important for costumes - you need to get all of them to unlock the platinum trophy.
Galactic Compendium: Spinal Control Unit
Note - This and two other secrets described below require the possession of the Guardian Collectibles from previous chapters. Only then will you be able to find them aboard Milano and examine them to start a conversation with one of the Guardians. You don't need to immediately examine the collectibles delivered to the ship. You can save them for later. Your last opportunity to examine them and go through the conversations is in Chapter 14.
Visit Rocket's cabin aboard Milano and find the Guardian Collectible inside. You'll have a conversation with Rocket which you can play out in any way you want.
Galactic Compendium: Broken Translation Device
Visit the lower level aboard Milano and find the Guardian Collectible there. You will talk to Groot, and you can do it however you want.
Galactic Compendium: Ravager Comm Bracelet
Visit Star-Lord's cabin aboard Milano and find the Guardian Colelctible there. You will talk to Gamora, and you can play the conversation out any way you want.
Archives: Collateral Damage
You can find the collectible during the first stage of crossing the planet Seknarf Nine. Soon after the first big battle you'll have to solve a few small environmental puzzles. One of them involves asking Rocket to hack into the panel shown in the image above, which was hidden behind a parasitic organism that you destroyed with blasters.
After unlocking the passage, climb further up the mountain and look for the secret on a large overgrown wreck.
Outfit: Guardians of the Galaxy 2014 - Gamora
The chest with the outfit is well hidden and getting to it will take you a while. As you cross through the jungle, soon after getting the previous collectible, find the blue hole shown in the picture. Squeeze through it to start investigating the secret location.
Locate a parasitic organism inside the cave on the wall and destroy it with blasters to unlock your way further.
You will reach a location with two monsters. You must defeat them alone, with no other Guardians supporting you. Focus on one monster at a time - try to first destroy its protection, and inflict damage only afterwards. Dodge and possibly fly a lot in the meantime, and try to reload your blasters perfectly.
Once the fight is over, locate and destroy another parasitic organism (picture 1). It'll unlock the narrow passageway and you'll be able to squeeze through.
The chest with the secret (picture 2) is in the last area of the cave.
Guardian Collectible: Chitauri Sear-Cuffs
You can get the secret in the process of solving environmental puzzles, during which you have to give orders to Gamora (sticking to walls and pulling Star-Lord up) and Drax (carrying the heavy block). It will happen some tome after defeating the strong blue monster.
Have Drax transport the heavy block to the location in the picture. This will allow you to climb to a higher shelf.
In the place from picture 1, though, you need to jump to the lower shelf (make a long jump). There, you'll find the secret you're looking for (picture 2).

You can get this secret right after locating the previous one. You must return to the where you solved the environmental puzzle, but this time perform the steps needed to unlock the exit from this area:
- get Drax to put the block under the cables,
- order Gamora to cut the cables - this will be possible only if she is able to climb on the correctly placed block.
A correctly solved puzzle will allow you to leave the huge wing of a bomber wreck, and you have to use this passage (picture 1). As you climb the wing, you will find the collectible you are looking for (picture 2).

You can find the secret soon after you get out of the slime, unlock ice attacks, and complete the first environmental puzzles that require them. Finally, you will be able to ask Gamora to cut the cables and unlock the path (picture above).
Examine the area on the left right after using the new passage. The collectible is on the ground.
Outfit: Five Horsemen of the Apocalypse - Groot
You can get the last secret in the final part of the chapter, soon after defeating two big blue monsters and asking Groot to use his skills to create a bridge (picture above).
Right after crossing Groot's bridge, you will reach the parasitic organisms shown in picture 1, which you can destroy with blasters.
In a new location use ice attacks on the waterfall to create an ice shelf.
Jump on the ice platform and then to an even higher one from there. You will reach the upper area where you can find the chest with the secret inside - see picture.
