Just got an email* to sign up to Humble Monthly Bundle and get XCOM 2 for $12 or approximately £10 post-Brexit. Considering I've wanted XCOM 2 anyway and it currently sells for £35 that seems like a good deal. Is there a catch?
* I think I downloaded a free bundle that was linked to here once and ended up on the mailing list. Check the emails when they come but any bundle in the past with games I'd like I generally already have.
