Well folks, u should know the background of Tremulous to know this game.
Well first of all you should know that Timbo is scottish.
Simply its Tremulous 0.1 released in 1987 november, so it's the anniversary of it.
Made for commodore 64, this game was the ultimate and first of all time first person shooter of that Era, beating the Operation Wolf and many of his clones.
The map is called ATCS 0.1, but the secret /noclip part of it.
Theese were the ancient times when grangers were white and very well noticable, so Timbo decided to turn them green, making them more hard to detect, creating the possibility to eggspam.

sry for the quick pwnage, download the emulator to own it.
Is it my turn?
