Another Reddit user, caroline-rg, had their own theories about the teaser actually somehow being real. However, saying that the “E” in an exit sign points towards E3 2019 stretches further than a well-executed Hands Across America campaign. A major point of this commenter’s theory revolves around there being three signs in the teaser with prominent “E”s, suggesting a full reveal will be at E3 2019.

The commenter also points to the YouTuber’s username “Cluserflu,” noting the Google results of this phrase brings up a vaguely relevant 2009 article of a potential Chinese flu outbreak, saying it being published the same year L4D2 was released is somehow significant. They also point to the video’s runtime, 2:10, as a reference to that date being almost a tenth anniversary of L4D2. The commenter points to the video’s title, which they note includes the date Novem(though it could easily be June 11, 2019) - the same month the previous two L4D games were released, even if they were released on Novemand 2009, respectively.

Reddit user gSh3p shared a detailed comment from the PC Gamer article that has since been marked as spam that stretches further than Mister Fantastic shaking hands with Elastigirl across the Grand Canyon - still, it's one heck of a conspiracy ride. The headlights of the car then illuminate a hand which ultimately shows three raised fingers, and the teaser ends with some classic zombie outcries. The teaser slowly pans over to a decapitated zombie head pinned to a store shelf by a pickaxe, and follows a trail of blood outside, where bullet shells litter the ground and detailed guts adorn a car. A downstairs room contains maps, blueprints and notes like “mutant fanatic” and “survivors location” suggesting somebody has been tracking the location of people following a zombie outbreak.

The final shot of Clusterflu961’s fake teaser.The teaser slowly reveals what appears to be a gas station safe house, complete with barricaded doors and canned foodstuffs. The video itself has the extraordinarily memorable title "20190611wVLACgXBSwO4eVv.021162_h264” and despite this unassuming moniker, managed to amass over 280,000 views over the course of a day.

The fake teaser, which can be found here, is the only upload from YouTube channel Clusterflu961, and the only detail associated with the account is that it originates from Canada. A suspicious teaser for Left 4 Dead 3 was posted on YouTube yesterday, and though it’s been confirmed as a fake, that hasn’t stopped fans from coming up with some absolutely wild theories surrounding the video.
