Prolonged Exposure

In 2 collections by Stratos

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.

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.

Needs more checkpoints. I think I know how to beep it but I keep falling into the water in the secound half! Maybe I will try it again in the future.

How'd I miss this one? Great test, great visuals, and great website shoutout ;)

Excellent map! Loads of tricky logic and a decent length. Feels great! And going back to a previous chamber to retrive a cube.... brilliant!

I'm amazed my poor old brain still works after figuring this one out. Nice work.
