The Map Maker here is co-author on Adexcoriatarium and this is published as a solo effort. Adex was tuff, a pretty good puzzle. With this scenario you basically get the same game. Might have a bit more flow to it, a little different design in some areas. Seven levels with the 7th a Net Level & very handsomely done too. These two scenarios, Adex & Exterminate, are very good for play, you won't finish in a half hour, unless you're a better man than I am Gunga Din! Worth the download, definitely!
