This collection is full of various, completley logical chambers. No tricks. These tests are like contraventions. No surprises.

This paticular testing track runs through a series of experimental chambers designed to test prototype testing elements. As such we shall need to know immedeatly if something goes wrong or does not happen the way we have intended.

This is a collection of chambers that test of well you think when you're about to die.

All these chambers have something wrong with them. The central core of this Earth's Apeture makes you go through the fixed version once you get through the broken one, assuming they can fix it. How much of this can you take?

When you wake up in a shot-up observation room overlooking an abandonded test chamber, a few questions come to mind; "How did I get here? What's going on? Do these questions have to be asked in this order?" Travel through Apeture's long-lost west wing and

A bunch of tests that involve physics. Gravity, recoil, inertia, gels, it's all good!
