Here is something you may not know! Sometimes, when using in-game voice chat, your character may open his mouth and talk when you talk! (it only works if it has face posing and if its on another player) As you can see, they move!










The secret phrase "bloxwich" is actually a place close to Walsall, where the Facepunch Studios are located.

• There is a little doll in a small room under the spawn point, it is unable to duplicate, or move. I dont know what it is a model after. (There is a purple one that is unspawnable on construct, but that can be duped and moved around.

If you explore down there and find that building, interacting with it will make it scream at you. Freaky.

You can weld your props to the sky. Im not joking. This sucks, especially for building and you accidently make a wrong turn or look in the wrong way and you welded it to the sky. It now will never move and will slam into the ground at incredible speed when picking it up.

One time, Facepunch decided to make versions of the C:SS and DOD:S models do not require both games. While the C:SS models look fine, the DOD:S ones look awful. (So you should still mount them)

Left 4 Dead 1 when mounted has it's own menu, while Left 4 Dead 2 doesn't. Kinda weird right?

I hope you learned something or found something here cool!
I made this for fun and i will add more to it :)
