Aperture Tag: The Paint Gun Testing Initiative is a Portal 2 modification based on the game Tag: The Power of Paint. It features the Aperture Science Paint Gun Device - a tool capable of spreading out an unlimited amount of Repulsion or Propulsion Gel - instead of the regular Portal Gun, new testing elements, such as a different version of the Emancipation Grill that alters the Paint Gun, a full, four chapter long campaign consisting of 27 maps, some of which involve reused Test Chambers from both Portal and Portal 2, as well as a modified version of Portal 2 level editor that includes cooperative support.

Aperture Tag: The Paint Gun Testing Initiative is available to purchase at the Steam Store. It requires Portal 2 to work, and features Steam Workshop integration, Steam Trading Cards, and a full developer commentary.


Aperture Tag takes place in the Aperture Science Enrichment Center sometime after the conclusion of the Portal 2 co-operative campaign. After a short intro, the player finds himself inside a Stasis Chamber in a Relaxation Chamber-like room. An unspecified amount of time later, an AI companion in form of a Personality Sphere, named Nigel, appears and greets the main character - a female Test Subject - commanding her to begin testing.

After acquiring the Paint Gun, the player is challenged to complete sixteen test chambers. At first, only the Repulsion Gel is available, although the second chapter brings an upgrade to the Paint Gun, allowing it to spread out the Propulsion Gel as well. When the testing is done, Nigel informs the player that the Aperture Laboratory Stability Stable Energy Reactor has to be shut down due to its redundancy as the Aperture Science now uses another, newer version of the device. A fast paced escape from the unstable reactor is what marks the end of chapter three.

The fourth and last chapter introduces a new design of the test chambers, that are now kept in an environmental style. These layouts include a forest, an arctic land, the Moon, and several more. The nine-chamber long testing track ends with an Unstationary Scaffold ride through a short trial with turrets. Nigel says goodbye to the player, and the player, having no way to escape, burns in a pit as Nigel sings "Still Alive".

An alternative ending is available - if the player goes out of bounds in the last test, he can find a control room with a switch that closes the fire pit. Nigel, instructed by GLaDOS, lets the main character go to the surface, which turns out to be another fake environment.


ValveTime stated Aperture Tag "looks great, it plays well, and it last 2-3 hours. Giving it good value for money." ValveTime praised the visual and level design for its gameplay mechanic and variety, level design structure, polish degree, soundtrack detail consistency and map scale without affecting performance. However, they also criticized the pacing of the story and dialog falling weak many times.[1]

PC Gamer rated the game 58 points out of 100, stating that it "lacks balance and grows repetitive, but provides a handful of good puzzle chambers if you're willing to pay for them."[2]

A general statement by purchasers of the game in reviews on Steam have been that it has a "poorly written script, sub-par voice acting, and general lack of polish". Others, however, have largely complained about the existence at all of a $7 price tag for a licensed mod, rather than the game being free of charge.[3][4]
