The Atlas Project is a server with two main things to do. There is a mini games world that just opened and it has 100 mini games to play.
If you get bored of games you can hop into the SMP and do survival. The SMP is run by the members so people vote on add-ons and anything new that gets added. It feels like a small welcoming community.
The server is age 16 plus. The SMP uses add-ons like Actions and Stuff plus Weapons and Tools and Over mob for more mobs.
