So recently I've heard about people finding posters with UFOs on them and some pictures of UFOs in TF2 and people were thinking it's hinting at a new game-mode Valve is making for TF2 that's been named invasion. I was thinking people were just overthinking things, yet,this sounded interesting. So what I decided to do is do some research on it just to see if anything actually comes up. I looked up "TF2 invasion pictures" in Google and the results actually came up with a supposed leaked video made by Valve in SFM called invasion and it shows a UFO invasion. Than I looked further in the search results and found on TF2 wiki a page about Invasion. I was pretty surprised. I opened the wiki page and it actually tells about what TF2 was going to be in one of it's stages. So I'm thinking that Valve is making a new game-mode based around what TF2 WAS going to be in one of it's stages. However, this is just my theory and it really could just be a big ass hoax.
