Testing focus: Lasers and Hazardous Liquids

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.

Really nice! More than just a follow-the-path walk through. Thanks!

Great logic challenge.

Seemed like a nice chamber, but I couldn't get past the mine-shaft section. I retrieved the laser cube, but I couldn't get over the pit.

This had some really clever puzzles (especially going into the previous chamber to get the necessary cube ) and some nice visuals to boot. It took longer than 20 minutes but it was worth playing.

I enjoyed that; relatively easy, but does require logical thought and really good fun :)
