Horizonsdawn MC is running Feed the Beast: Unleashed 1.1.3 with all extra mods enabled. On top of this we've added Galacticraft to allow anyone and everyone to go to the moon!
It is also worth nothing that most vanilla tools are currently disabled in favor for thinkers construct. This may or may not change in the future.
We have few and simple rules:
Don't be a douchebag, treat people with respect.
PVP is on but moderated, please see below.
Use common sense.
No means no, even in minecraft.
If you enter an area dedicated to PVP don't whine if you die.
Please do note the server is still being developed and there are many areas where we can improve. If you feel that something isn't working working very good don't hesitate to talk to the staff!
