Sixth Worlds Shadows bundle is for Shadowrun 6E. There is also a Shadowrun Sixth World Essentials bundle which I have all but one item (guess you can count the core book in the bundle which is a different city than the core book I have). This variable price bundle is currently at $41 and gets you:

Sixth World Companion (210 pp)
Hack & Slash (186 pp) - core Matrix rulebook
Body Shop (194 pp) - core augmentation rulebook
Shoot Straight (160 pp) - "provides runner-to-runner advice in a range of areas, from covert ops to con games to making sure you don't blow your big score in one place"
Shadow Cast (178 pp) - "explores 20 different character archetypes"
Emerald City (208 pp) - Seattle sourcebook; I suppose this may have repeated material from my Shadowrun core book
Astral Ways (186 pp) - metaplanar setting book
Null Value (146 pp) - "lists ten threats that can fuel campaigns, character development, and more"
Wild Life (194 pp) - core critter rulebook

Even at $40+ it's a nice bundle though sadly lacking adventures. Still, will buy it since I have the base bundle.
