PORTAL TRIAL: LASERS

This is the first of a series of test chambers. Each Portal Trial test chamber will feature only one mechanic (e.g: lasers, light bridges, orange gel, etc.)
In this one, it is obviously lasers. It may be simple, but it is also unique at the same time (if you know what I mean.) The next Portal Trial is likely to be funnels (the blue tractor beams first seen in Wheatley Laboratories.)
