Abzû comes out on PC and PlayStation 4 on 2nd August.
It looks like Sony has snapped up the underwater adventure game as a (timed?) console exclusive, which is probably why it's a part of the PS Play Program. This means PlayStation Plus members get 20 per cent off by pre-ordering.
Abzû is from Giant Squid, the studio founded by Flower and Journey art director, Matt Nava. Aoife took a look at Abzû in the video, below.
