|Half-life 2 will run on any system with 128mb of RAM or more, that has a DX 6.1 compliant video card or higher. |
I use to run HL2 on my Balance 1ghz via C3 laptop with 128MB's of ram and built in S3 unichrome DX 7 graphics hardware. BUT, I have not run HL 2 in over a year and I know valve totally removed support for Win98 and support for other things. Not that the actual application could not run on 98, but valve decided in their unremarkable wisdom to disable it.
But if I can run the game in 98/XP with that crap hardware, you can run it too, just don't expect anything great.
