Prolonged Exposure

In 2 collections by Stratos
That Laser Collection
3 items
Fear the Reaper - The complete collection

Testing focus: Lasers and Hazardous Liquids
Difficulty: Easy-medium / medium
Expected play time: Several minutes to, say, twenty?
Version: 1.1

This map features Thermal Discouragement Beams, Toxic Goo and Fizzlers, with some Laser Redirection required. It doesn't focus on laser relays though, it actually revolves more around logic. No quick finger needed, just logic.

The name of the map, Prolonged Exposure, refers to both the use of lasers and the deterioration of these otherwise pristine test chambers. The artstyle of the map is the same as of the Penrose Collection but this time around the walls are going to be opened up a little to reveal the underlying rock.

The map was originally supposed to enter in the Heavy-Duty Super-Mapping Super-Contest on ThinkingWithPortals, but under the circumstances I couln't upload it in time. So here it is now, I hope you'll like it. If you do, I reccomend you subscribe to me for more maps. :D

PS: I hope you'll forgive me for taking a break from the Penrose Collection for this one.

The thread for the map on ThinkinWithPortals can be found here:


Version 1.1
- Added autosaves.
- Fixed some indicator lines and other details.
- Made the dried up goopit less deadly. (Still deadly though.)
- [Possibly] fixed my custom cube skins not showing up properly.

Pretty cool. Puzzles made me think, but I never really got stumped for too long. A perfect mix.

Played this map a couple of years ago. Great fun! Especially liked using the tunnel to get around the broken cube dispenser. Activating a laser target from the side is a bit edgey, though. Pun intended. Thanks!

@Telluric: Thinking with Portals shut down in December last year.

The cube dropper still has the normal Aperture logo on it.

How did you make the special Aperture Southern District cubes? The look really cool.
