It’s easy to look why the Portal games have this kind of devoted fanbase. The games feature no combat to talk of, and (besides wonderfully-written non-human characters) the mind-bending nature of the games’ puzzles speak on to what gaming is at a basic level: progressing through increasingly difficult levels with a purpose to a memorable ending.

So, Portal fans are fairly obsessive over the franchise, etching music into stainless-steel, creating mash-ups, and filming several fan films, most depicting what it might really be prefer to have a portal gun. This week, another fan tribute to the series has appeared on YouTube.

Titled Portal: Survive!, the fast film starts with an outline of Chell, the player character within the Portal games. It then moves right into a little bit of backstory, depicting the ultimate moments of the (human) scientists working at Aperature Laboratories. The events and references seen within the video are taken from the tale gleaned from the Portal games, in addition to the online comic Portal 2: Lab Rat.

According to the its YouTube description, the movie was created by Colin and Connor McGuire for only $500. It was filmed at YouTube Space LA, a production house in La that helps YouTubers create original content for the positioning.
