This new Rifts Core Megabundle presents a giant array of rulebooks and major supplements for Kevin Siembieda's Rifts from Palladium Books. This Megabundle brings back nine titles from previous offers and adds nine major supplements new to the Bundle of Holding – everything you need, by a wide margin, to run a complete campaign of mind-blowing adventure across a future Earth shattered by countless otherworldly invasions.
Rifts is set centuries in the future. Magic energy has flooded back to Earth, fracturing space, tearing through reality, and opening doors to supernatural realms, strange dimensions, and alien worlds. From these portals emerge mythical gods and Elemental creatures, hordes of demons and monsters, dragons and creatures of magic, Shadow Beasts and the undead from dimensions of darkness, and aliens from many realms.
Earth itself has become an alien landscape where the people, cultures, technologies, and madness of alien worlds and realities collide with our own. It is an environment simultaneously familiar and alien, wondrous and horrifying. The magical, supernatural, and alien may come to you, or you may find them. Technology and science co-exist and clash with magic and psychic power. Robot warriors and power-armored troops battle dragons, demons, and magicians. The setting is one of constant change, conflict, horror, wonderment, magic, and endless possibilities.
We provide each title complete in .PDF. Like all Bundle of Holding titles, these ebooks have NO DRM (Digital Restrictions Management), and our customers are entitled to move them freely among all their devices. (By publisher request, the DriveThruRPG versions of these files are inobtrusively watermarked.)
Ten percent of each purchase (after gateway fees) goes to this Rifts Core Megabundle's designated charity, the Diana Jones Award Emerging Designer Program. Each year, the Diana Jones Award for Excellence in Gaming, a 501(c)3 nonprofit, amplifies the voices of up-and-coming game designers by featuring them during an expenses-paid visit to Gen Con. The global Emerging Designer Program focuses on creators from marginalized communities.
The total retail value of the titles in this offer is US$200. Customers who pay just US$19.95 get all seven complete modules in our Corebook Collection (retail value $71) as DRM-free ebooks, including the Rifts Ultimate Edition core rulebook (retail price $20), plus the Rifts Primer (retail $3); the Adventure Guide (retail $12.50), Game Master Guide (retail $13.50), and Game Master Kit (retail $5); and Index and Adventures V1 and V2 (retail $8.50 each).

I'm not a fan of Rifts, but opinions differ. By now this is a fairly old system and I'm not sure that any of these books were published less than twenty years ago - I should add that I haven't checked every one, I've just looked a couple up at random - and the game mechanics etc. are a little dated.
But if you like the system and/or setting and want more for it, it's probably worth a look.
