PlayStation Plus subscribers can now join Vita shooter Killzone Mercenary's open beta.
The handheld FPS is due to launch in Europe in two weeks, but Plus members get early access to its online portion today.
A demo of PlayStation 3 platformer Puppeteer is also available to download today, again only for Plus subscribers.
This week's line-up of new PlayStation Store content also includes digital versions of this Friday's three big retail releases - Saints Row 4, The Bureau (both £49.99/€59.99) and Splinter Cell: Blacklist (£59.99/€69.99).
Oh, and there are some The Last of Us costumes for LittleBigPlanet 2.
