Aperture Tag: The Paint Gun Testing Initiative

Aperture Tag: The Paint Gun Testing Initiative is a Portal 2 modification featuring gameplay focussing around the use and manipulation of the Gels featured in Portal 2.

Story
A test subject wakes up in an Aperture Science Relaxation Vault ready to begin his test. He is introduced to Nigel, a personality core and his test associate. He then is put through a series of tests featuring the Aperture Science Paint Gun, Aperture Science's final product. When the testing is over, Nigel was surprised that there was someone to complete every single test chamber and thinks that he is the proper one to deactivate the old Aperture Science Energy Reactor, the energy supply of Aperture Science, as a new one was built. Nigel is really surprised that he made it through so easily and decides to put him through another round of tests.
