Chisel makes you wonder what you can't do with Marathon maps. For anyone doing serious scenario work... if you're not using Chisel, you're wasting your time. This package is for folks who haven't used Chisel yet... or haven't updated their versions in a while. You can always grab just the Chisel app, if you're up-to-date with plugins... or go visit Mike's Chisel World, and see what he has to say. (Of course, all of Mike's Chisel-related stuff is available here, as well.) PLATformer 1.0 is included in this package. Latest release includes new versions of Wot Dat Tag Do Den and Texture Munger. The 2.1.6 update does one thing only - it enables Chisel (again) on 68k Macs. You DO NOT NEED this if you have a PowerPC Mac and have v2.1.5. (If you don't have Chisel, getting this version won't hurt... you simply don't need to UPDATE to it if you have a Mac that was built after 1994.)
