The Last Of Us Walkthrough Part 54 – Chapter 8: The University (Dormitory Courtyard to Lab Grounds)

Outside once again you will see Ellie over to the left. Go over to the gate and interact with the Yellow wire there. Joel will look at it then straight at the generator he needs to power it. Grab it and wheel it over to the power cord. Pull it in then head over to the left and search trash pile for some Crafting Items. Now go back to the Generator, fire it up and the gate will open. Ellie will come through on Callus, then Joel will mount up. The two have a conversation about the Clickers that Joel encountered. For now just head for the far side of the Courtyard and through the archway in the back left, nearby the door Joel came into the Courtyard through.

Once through the archway turn to the right and hop the barricade there. This will lead you over to the Lab Grounds. Both Joel and Ellie are a but unnerved by the fact they have yet to meet a single person on the campus where Toommy thought Ellie was going to be taken. There are a lot of items to find this in this area so approach the tents on the horse then hop off. The first tent has some Crafting Items on the shelves to the left. Now head out of the tent and look over to the left of it. You can sometimes find a hatchet sitting there so grab it. Remember it offers instant melee kills so it it very worthwhile to grab. Now head down to the third tent. Search the fallen rack to find Parts and Ammo. Check the next tent over for more Parts. Now head for the far tent and search it for a Firefly Pendant and some Parts.

Head over to the right and and down to the gate there. Joel will try it and find it is rusted shut. Head back up the slope and look to the right. By the pillar you will find a dumpster Joel can interact with. Grab it and bring it over to the top of the slope and then let it go to slam it into the gate to force it open.

Head on down the slope and grab the dumpster again. Drag it over to the truck on the right and place the dumpster against it. Now you have a way to climb up onto the truck. Do so and make for the broken windows. Climb on up to it and you are inside the Science Building. Hopefully here you will find some live Fireflies and not just Infected or more corpses.
