Hmm. This bundle is looking to be rather meh in comparison to the great first bundle, with several repeats, one early access title, two multiplayer-focused titles (calling them single-player is a stretch, but as usual Legends of Aethereus and King Arthur's Gold added a pointless bot mode just to be able to add the tag) Also, the vast majority of these games are available DRM-free, but based on the first bundle, it's likely to be Steam keys only again.
King Arthur's Gold - Bundle repeat. Multiplayer-focused. DRM-free available.
Little Racers Street - Bundle repeat. DRM-free available.
Vox - Bundle repeat (twice). Also alpha. DRM-free available.
Iesabel - As far as I'm aware it's a fairly serviceable single-player game. Not a repeat. DRM-free available.
Legends of Aethereus - Multiplayer-focused. Not a repeat. Steam-only,
despite the developer's pledge to make it available DRM-free.
Kairo - Not a repeat. DRM-free available.
Blue Toad Murder Files - Not a repeat. Steam-only, but doesn't actually use any Steamworks features.
I'd like to mention re:Vox that the developer is one of the few not to have given up on updating the DRM-free alphas despite making it onto Steam. There's been a rather unpleasant trend where, once greenlit, devs have just left non-Steam versions to rot.
Edit: Correction to King Arthur's Gold.
