Editing Gamma World (section)

===Fifth Edition (2000)===
The 5th version of ''Gamma World'' was a supplement for the science-fiction game ''[[Alternity]]''. (In a nod to ''Gamma World'''s reputation for being repeatedly revised, the book's back cover states "That's right, it's the return of the ''Gamma World''".) The ''Gamma World Campaign Setting'' ({{ISBN|0-7869-1629-X}}) was a 192-page softcover book written by Andy Collins and [[Jeff Grubb]], published in 2000 by [[Wizards of the Coast]] (WOTC), only a month after WOTC announced its cancellation of the ''Alternity'' line.  This version of ''Gamma World'' is unique as the only one not to have accessories or supplements.
