Tomorrow's going to be a good day for PlayStation Plus subscribers, as they'll get their hands on Zen Studios' Star Wars Pinball free-of-charge. It's the latest addition to the free game line-up for the monthly service – and that's not all.

Capcom's Darkstalkers Chronicle: The Chaos Tower, which originally released on PlayStation Portable, will also join the line-up, and is fully compatible with PlayStation Vita.

In addition, some discounts are available for upcoming games as well. The long-awaited DiveKick can be yours on both PlayStation 3 and PS Vita for $7.99, two dollars off the regular price. The puzzle/shooter game Ms. Germinator is also being offered at that price.

Last but certainly not least, PS Plus subscribers will have access to a public access beta for Killzone Mercenary, trying out its multiplayer mode for the first time. We've played it and the beta's awesome.

One game that will leave the service is the side-scrolling action/puzzle game Dokuro, so get it while you can.
