- P4 2.5Ghz CPU (or equivalent)
- 512MB of RAM
- 128MB graphics card (ATI 9000s and higher, GF 4, FX and higher)
- 2GB of free hard drive space
And yes, we're talking about minimum requirements here. The most surprising item is the processor, since even Half Life 2 required only a 1.2 GHz Processor with 256 MB of RAM. I know Half Life 2's performance would be terrible on such a machine, but I cannot believe the CPU requirements would double in a year. Edit: someone noted that it could be another April Fool's joke. Let's wait for a confirmation folks...
