Q: What do we know about the custom tools to build our own maps in Halo 2 Vista?
A: Quite a lot. The original tools found for the first port, Guerilla, Sapien, and Tool, will make reappearance; this time included on the disc. The H2V team has stated that this time around, we will be able to customize a lot more than Sapien had to offer, as well as creating new and improved textures and even customizable shaders
the tools are the SAME! as they are now...i can see ALL THE SWEEET MAPS ON XBOX NOW!
