Minecraft: Story Mode

Story related, can't be missed.

See below for the walkthrough:

Chapter 5:

Choice 1: Tried to help Ivor

• As players navigate towards the throne room, an unexpected encounter is had when Milo comes out of nowhere and bashes Lukas over the head. An uninitiated dialogue is procured from that, when a quick time event pops up to strike back. The anything but nice welcome is broken up when our friend, Petra, calms Milo down from what could have been disastrous otherwise.

Choice 2: Ran from the guards

• Jesse, Petra and Milo are shown shimmying from a ledge to be centered below the window. Uninitiated dialogue beings until coming to a sudden end, when the player must rapidly press a button to apply ladders to the wall.
• After climbing up and over the window, Jesse and company will sneakily walk forward, only for guards to heard and "seen" coming in through the door. This preconceived notion is put to rest as the voices of Ivor and Lukas are heard and then they are physically seen moments later.

Your story bridges together at this point.

• Uninitiated dialogue begins and is determinant on your chosen path from chapter three.
• Interact with blocked doorway to learn about a secret passageway that requires a lever to activate the redstone circuits to open it.
• Interact with the cobblestone generator twice and with the dead bush twice. You will acquire one cobblestone and one stick. From there, interact with the crafting table to craft a lever for the secret passageway. Place the cobblestone at the bottom of the middle column (middle bottom) and the stick in the middle of the middle column (middle middle). Press or if you encounter any difficulties, that you may be able to see the recipes.
• Interact with the lever slot, located on the ground behind the blocked doorway.
• Interact with the chest and find a spawn egg.
• As suggested by Petra, throw the egg and give it a shot [to see if it actually spawns what it says (sheep)]. Uninitiated dialogue will proceed afterwards.
• Walk directly forward until you find the Eversource. Uninitiated dialogue continues after that. The Founder and Blaze Rods will make a grand entrance not too long after with continued dialogue options.

Major Choice:

Tried to rescue Isa or Tried to help Lukas.

Choice 1: Tried to rescue Isa

• Rapidly press the button that is shown on-screen to save Isa from falling.
• Lukas stumbles by you towards the cliff and subsequently falls off to his probable death in the eyes of Jesse and the Founder. Aiden sweeps in and pushes off Jesse and the Founder to meet what looks like the same fate as Lukas.
• The chapter ends here.

Choice 2: Tried to help Lukas

• Move your cursor over Aiden in attempts to strike him. However, your plans are foiled as he dodges to the right of you and runs off in a hurry. Due to not saving the Founder by trying to rescue her, she falls off after dangling for an extended period of time. Jesse scurries over in awe of what just happened, only to get pushed off the edge as Aiden pounces on the opportunity. While in slow motion, Jesse and Lukas are seen in disbelief by the events which transpired moments ago as Jesse falls to what many suspect as an inevitable death.
• The chapter ends here.

You should earn this trophy after meeting the above requirements!
