Gabe Newell Simulator is a weird 2D shooter made by Trent Steen, Liam Yager, and Alec Steiner for the PewDiePie vs. Indies Game Jam in November 2014, in the midst of Kim Kardashian breaking the internet, CNN freaking out about ebola, and Trent struggling to get his game through Greenlight.

It's kind of entertaining.
