Remember the ye olde days?

The ye olde days where we only had 1 direction in sprites?

Where we only had 1 floor tile sprite?

Where we didn't have smoothwalls?

Well, due to space-time-bluespace rifts caused by scientists stealing everything with the telescience pad, a fragment of spaceman history has been restored!

Features:
Due to the scientists fucking up time and space and causing this, it's their job to fix it. You are only able to access this area via telescience.
Authentic oldstation toolboxes!
Authentic oldstation walls!
Authentic oldstation tables!
Authentic oldstation tasers!
Authentic oldstation inhabitants who hate spacemen with 4 directional sprites!

Q&A:
Q: Why isn't it an away mission?
A: The point of this is so we can try testing the waters on space content that is on the map itself and can be accessed via telescience or teleporter mishaps. It's small, has a few mobs to kill, has some minor loot, should allow us to see what player opinion is on this stuff to beam over to with telescience.

Q: Why did you use the shitsprites?
A: So it would be different from the rest of the stuff floating out in space to try and give the area a unique feel to it.
