King Arthur's Gold is a very cool little game, in which 2 teams build castles and traps and then attack the enemy to get their flag. It is like a combination of Minecraft (Teraria) and Team Fortress 2. There are 3 classes - builders (place and destroy different blocks), knights (fight whit a sword, throw bombs) and archers (you guess that one). You should definitely give it a try!

I am not sure if I had used that code, but I have finished the game and I still haven't deleted the photo of it, so can somebody tell me what is it for?  

And also I wonder if you can do something whit the computers in the control room of Explorer XLII. All I see is "Load Error".
