Aperture Tag, the Portal 2 mod where you wield a Paint Gun instead of a Portal Gun, will be officially released on Steam this month. According to the developer's announcement, Aperture Tag will cost $7, and will be sold at a 30% discount during its first week.

Looks like Wheatley's space travels took him all the way to the Mun from Kerbal Space Program, with a little help from redditor Technotreese. Kerbals have quite the penchant for testing, so Wheatley should feel right at home.

Is this... The Valvengers? The Hulk, Hawkeye, Iron Man, Nick Fury, Black Widow, Captain America and Thor (poor Thor) all transformed into Valve characters. With the Scout and the Soldier from Team Fortress 2 and a zombie from Left 4 Dead, teaming up with Gordon Freeman, this team probably wouldn't function smoothly.
