Modern/Sci-fi Rules Extension of D&D 5th Edition

Hey everyone! I've been designing and play-testing a 5e-compatible rules supplement and campaign setting called NearFuture5e Shard City. At its core are the new character classes, which are "spiritual" near-future equivalents of the classic medieval fantasy classes. The cover art here shows you three examples of that:

The modern/sci-fi \"Warrior,\" \"Rogue\" and \"Spellcaster\"

Anyway, the project is now on Kickstarter, for those interested: https://www.kickstarter.com/projects/gaminggeek/nearfuture5e-shard-city-rules-supplement-and-campaign-setting
