Shadows Have Evolved
The year is 2070. The world is not only Awakened -- it's wired. Cyber and bioware implants make your meat body better-than-flesh, while the wireless Matrix enhances your perceptions with hyper-real senses. Deals are made in steel and lead more often than gold or nuyen; success and failure live only a razor's edge apart. Creatures of myth and legend walk the streets, while the arcane skills of spellslingers are in high demand. Above it all, monolithic megacorps bleed the world dry, sabotaging each other in covert cutthroat competition as they go to war over the bottom line
You're a shadowrunner, a street operative, scratching out a living on the mean sprawl streets. You may be human, elf, dwarf, ork or troll. From lethal street samurai to well-connected info brokers, spell-slinging mages or code-cracking hackers. No matter what, you're a professional --corporate pawn or "deniable asset," you get the job done.
