You can now get WW2 strategy game Hearts of Iron 4, Early Access pirate shooter Blackwake and sandbox RPG Portal Knight as the early unlocks for July's Humble Monthly Bundle. Subscribers can play the games now, or if you want in for one-time only, it'll cost $12.

Hearts of Iron 4 is the standout. It's one of the best WW2 games around: it has all the depth you'd expect from a Paradox grand strategy game while still remaining easy to pick up, as Rob said in his review.
