You can try Dead Space

no i tried dead space, its not that good
and siren looks good but it's a psn game so you cant rent it i believe

 Trust me its worth the 39.99 $

But dont be fooled from the first Episode ! Its only about 3 minutes and it gave me a bad first impression of the game but  each Episode after that is alot longer and alot more freakier than the first !

Enjoy, your decision was just made for you XD

its on Blu-ray too , its called "New Translation" the one on PSN called "Blood Curse" , they are the same game only the PSN one is censored.

What PSN games do you own? For the price of a rental (~$10) you can purchase something like Flower, Pixeljunk Monsters, PixelJunk Eden, Super Stardust HD or shell out a little more for Wipeout HD. With the exception of flower, those games will keep you entertained for more than a short rental period.

naw i have quite a few psn games, i want to try a horror game on ps3

^ Echochrome isnt scary ....... but its a PSN game that still gives me nightmares!
Does that count?

Do you have Siren: The Blood Curse? I've heard that's pretty scary, but it's PSN only in north america.

Recommending games is hard if we don't know what you already own.

there is a demo for Siren on the Store and let me tell ya it's f***ing Scary :p

I'll get it later short on cash now
