Hero 4E Campaigns Bundle is the third Hero 4E bundle from Bundle of Holding. I've bought the previous two. Not sure that completes Hero 4E but if not must be close since this is a small $15 set price bundle.

Cyber Hero
Fantasy Hero
Fantasy Hero Companion - no cover, I'd guess copyright issue
Fantasy Hero Companion II
Horror Hero
Kazei 5 - Hero Plus (i.e. PDF-only) sourcebook set in a cyberpunk anime world, no cover but probably never had one
Ninja Hero
Western Hero - no cover, I'd guess copyright issue
