Now that Gamma World has been released to the premiere stores, I can share some cool add-ons that one of our local RPGA/LFR DMs (Matt Vincent).

I am a huge fan of 4th Ed D&D and is why i decided to buy GW. Over the past few weeks I have managed to purchase all three box sets for Gamma World 7th Edition from Ebay, and got the collected blister cards from druvethrurpg. It was pre 3 and 3.5 system which was a step above 2nd edition but not quite reaching 3rd edition complexity/rule set. The version of Gamma World is based largely on 4th edition Gamma world Published in 1992. This is a 5th edition compatible version of Gamma World. Gamma World: While technically a different game line, uses identical mechanics and is often seen as a subset of vanilla D&D, to the point that the AD&D 1st Edition Dungeon Master's Guide even had sections for converting AD&D characters to Gamma World characters and vice-versa.Buying the 3e Gamma World PDF from DTRPG, stripping the no-password encryption so I can edit a page from it in Photoshop, digging up the right font (Garamond) and size (9.5pt), adding a blurry 1 pixel black glow to the font to give it the same look as the scanned image, then printing and photographing the page… once I decide on a dumb gag.
