Sony has updated the PlayStation Store with PS3 demos of MotorStorm: Pacific Rift and Brothers in Arms: Hell's Highway, neither of which ask you for a penny.
The MotorStorm demo (617MB) features the Rain God Spires track and can be played offline on your own or with a friend in split-screen.
We're not sure what's in the Brothers in Arms demo, despite scouring the Sony US blog to dig up the post when it came out there two weeks ago (interesting detail: 1.21GB), and the Ubisoft website and that. What we do know is it's the same as the 360 one.
Besides those two, there's some downloadable add-ons for Eye of Judgement ("Set 3", which goes for GBP 6.99 / EUR 9.99, and Biolith Rebellion SET.2 and SET.3 Combo Pack for GBP 10.49 / EUR 14.99), and the Firestone Country Club for Tiger Woods 09 (GBP 4.99 / EUR 7.99).
Rock Band fans, meanwhile, can content themselves with Motley Crue's Dr Feelgood album, for which individual tracks are GBP 0.99.
Finally, there's a Killzone 2 multiplayer theme and Far Cry 2, PAIN and Tom Clancy's EndWar trailers.
