Cave Johnson here. I've just been informed that a Mr L.B. from our programming department has been unwell recently. Sorry about that, it's probably the micro-parasites we put into your keyboard. Don't worry about it, all they do is make you feel unwell but actually you're fine - apart from being full of parasites feeding off your blood. I've also been informed that our friend Mr L.B. is a little irritated at how long these pre-recorded messages are getting. With all due respect sir, you're an idiot and we've put more parasites into your keyboard. Cave Johnson, we're done here.


Welcome to Axiom, an ambitious monoportal map with multiple test chambers. There are, in total, four tests of increasing difficulty: three small tests, each focusing on one gel type, and then a final challenge with all three gel types. Each test has only one stationary orange portal, so you'll have to use your blue portal to manipulate the gel in clever ways.

Gel maps and monoportal maps are both very difficult to create, so combining them was a real challenge. I hope it's paid off.

An "Axiom", in logic, is something which is assumed to be true, a constant. In this map, the orange portal is stationary - it is constant, assumed to be true, hence the name.

Difficulty: Medium-Hard

Music: Portal Stories: Mel - Acceleration by Harry Callaghan/Harry101UK

Super fun map, had some difficulties with the blue gel in the 4th room, but after watching the video, I discovered I just made it harder for myself than it needed to be. :steamthumbsup:

Crazy good chamber :D

Nice puzzle! Gel in the last room felt a little messy but was very much worth the replacing of gel types on a single surface. I had thought the name came from the composition of three axiomatic gel setups, but the listed interpretation is nice as well.

The level was amazing. I got stuck at the end for a little bit, but I figured it out. Keep up the fantastic work.

Excellent map! I was going to complain about the fact that the final jump across to get the conversion gel in the exit room was an annoying tricky gel timing ninja move, but I actually did it! Then I watched the video and found out there was a solution that really wasn't that hard at all! Thanks for your work!
