When you return to the Tower talk to Alfie for this mission. Go to the fishing village and go under the bridge. Climb up on the concrete part in the water and take the door that’s open on there. Climb the yellow pipes up to the first platform. On that platform take the second yellow pipes up to the next platform. On the next platform that the other climbable thing until you make it to the red door and unlock it.
The Retouched update for Dying Light that improves graphical features has been released; here's how it compares with the Enhanced Edition.
I remember playing this for the first time on the PS4 and it knocking me sick and hurting my eyes due to the horrible motion blur and FPS.
Played it a lot on pc a year later. Then again on ps5 once they dropped the 60fps update. I'll be giving it another go. Mad how they have kept updating this game for 10 years.

Hey Survivors! Tymon here, your favorite Dying Light Franchise Director.
It's been an absolutely wild month here at Techland! We're in the thick of what I'm calling the "Summer of Dying Light," delivering updates and big news across all three Dying Light games. Just a few weeks ago, we dropped the first gameplay for Dying Light: The Beast, revealed its release date, and kicked off pre-orders (if you haven't seen it, check out my last dev blog). I'm incredibly proud of what we're building with The Beast - it’s the culmination of more than 10 years of experience in open-world survival horror!
But here's the thing: we never forget where we came from. That's why, this week, we're not just looking forward - we're rolling out significant updates for both the original Dying Light and Dying Light 2: Stay Human. We promised to support our games for a long time, and we're committed to continuing that support, right through and beyond the launch of Dying Light: The Beast.

It has been more than ten years since Dying Light was released, but what happened to the $386,000 'My Apocalypse Edition' of the game?
Wtf did this edition come with ? A real helicopter and a real zombie virus ?
Wonder how stupid you have to be to not realizing how to do this simple climb up quest.
I think this has been my favorite mission in the game so far. Especially jumping down into the river after reaching the top, that was a fun fall.
Dying Light's exactly the zombie game we deserve, but not the one we need.
