Hitting the wooden medic in door 1, he will say MeeM, also hitting certain targets in that room makes funny noises for some reason.

Looks like it's the great come back.

In the Room 7:
At the left of the room, while noclipping and going to the barrel tower. A bottle/wine from TF2 is hidden and while pressing E, A line is played and i'm very sorry if i can't hear what he exactly say. ^^'
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
In the Room 9:
At the right of the room, If you bring the rectangle thing to Barney, he thanks you for founding this thing and he's go to create a new map then unlocking a secret room where Barney create a map called "King of the Hill Meth" with the computer.

You mean Room 9 not 8

Oopsie. Just edit my post and thank you for notice the mistake.

In the Room 11:
If you try to go through the whole maze, you can found a dead end where a Wooden Heavy is. Trying to shoot, hitting or explode does nothing.

Room 11 teaser:
Entering room 11 in the previous Advent calender will lead to HL1 G-Man before throwing the player in a room with a radio teasing the 2022 Advent Calender.

ROOM 6:
Room 6 is inaccessible with only a QR code leading to a video of two guys escaping a room before shutting it down.

TF2 Target Mannequins:
1st Medic Target Mannequin: Room 1 (shooting range)
2nd Medic Target Mannequin: Room 3 (Too Many Crates)
Heavy Target Mannequin: Room 11 (Maze)
[The reward video for completing the maze involves Heavy]

In the Room 7 again:
If you open the door from Room 7, there is a rare chance you can hear a voiceover "In a different place. In a different time, time, time..." from the first Gmod Advent Calendar when completing the map. This trigger only if you open the door first, close and reopen the door doesn't trigger the event.

In the Room 8:
In one of the corner of the soccer field, there is a hole where you can actually fall it. but if you go further, you can find a piece of dead tree model, the only non-Christmas tree of the map when there are only firs for making Christmas theme. This can be also achieved by noclipping.

Well done

There's a binary code in the Gmod advent calendar video. The binary code says: 1010100 1101001 1101101 1100101, I have translated the code it to: ��n, I don't what it means and i hope someone will help me figure it out.
