AMD Athlon 64x2 4800+ or Intel Core 2 Duo, 1Gb RAM, 3D Hardware Accelerator Card Required - 100% DirectXR 9.0c compatible 256MB (Geforce 7800, for example).

I know it's just recommended but if u can't play it with the highest sets well... I'm afraid, I'll lose on some visual experience :)

Sure it'll be Scary, the trailer is not the game :)
