No new HB bundle giveaways?

One key per tier.

1 key per tier, that happened.

Sega happened.

Sega policy. 1 key per Tier makes them really annoying to give away but there will still be a few for T1.

One key per tier. BTA can be given away only as this package: http://store.steampowered.com/sub/52874/
But since it is terrible for CV, don't expect people to buy it only to give it away.

I think that HB changed their policy this way for all upcoming bundles, not just for this bundle from SEGA.
