makes it easy to get into the Voxxel editor, and make something you can play with right now.

You can make your own map, generate a AOS map, or save a map from a server by pressing F1. Then jump in and pop some trees and sniper decks about, and play with your friends, in just a few minutes :)

Not to hijack your topic, but I have also created a series of tutorials that cover the basics of Mapping for Ace of Spades. Starting with nothing, and ending with a map that has trees and structures.

You can view them on my website:
