Alright, look. This was pretty simple
1. Disable all the addons
2. Make a server called Shirt_Block Mesa
3. Once you log on you will have 5 types of bricks
4. Make a door with these bricks
5. Name the door handle Let_Me_In
6. When you click the door handle, it will open
7. You will see a pitch black room inside, go in
8. The door will close behind you, do not try to open it! Or you will never get the shirt
9. There will be a floating torso with the shirt on it
10. Come close to it, it will activate
11. You gain a health bar, and a sword named "Mesa_Killer"
12. You must fight the torso, however it shoots deadly default horses at you
13. Once you defeat it, it will pop
14. The room lights up to show you inside of Half Life 1
15. Gordon Freeman gives you a shirt
16. Everything will zoom out, and you will be at your character menu
17. You will have the Block Mesa shirt, along with a message saying "Good Job [username]"
18. Put it on, go back to your server
19. DO NOT LEAVE
20. There will be only one brick, a 1x1 in your brick menu
21. Place a one with your favorite color on it right where you were
22. You can't leave with the shirt, so you have to leave something to cover for you
23. Leave the server, and never come back
24. If any server is by someone named "LegitName"
25. Do not go to it, this will only happen on the first day
26. If you made it past the first day !CONGRATULATIONS!
27. Enjoy your shirt
28. Realize your are a giant noob and an idiot
