So after some extermination, I found a way to get outside of Pitfall. It's pretty simple to do and doesn't require that much effort. Unfortunately, Pitfall is pretty limiting in terms of object quantity, however I'm sure there are some people working on that. Anyways, here's the video, it explains how to get outside and how to get around some of the setbacks of forging out there. Enjoy!
Halo 3 would argue with you. Anyway, thanks for pointing that out Pokephile! I'll probably try my hand at something out there even with the block limit... I promise nothing.
You couldn't forge much on sandtrap... Sandbox perhaps? Anyway, I thought they were both considered Forge Canvas's.
