Sorry about the double topic, but I thought it belonged in both.
Thats right! If you own a Nvidia product, you will get the following games FOR FREE:
-Half-Life 2 DeathMatch
-Half-Life 2: The Lost Coast
-Peggle Extreme
-Portal: The First Slice

These games are distributed by Steam, so that means you need a Steam account to get them. (For those who dont know, Steam accounts are free)

If you own a Nvidia product(which is probably why you are here), then go to this page.

HL2 DM and LC are both free, and Portal is just a demo. Peggle is an arcade game. What a deal from Nvidia.

OMG FINALLY I CAN GET A FREE VERSION OF A GAME I DIDN'T PAY FOR ORIGINALLY!

Does this mean I can play mods that use the source engine?

I guess, but I alredy tried with Garrys Mod and it didnt work XD

Im still trying to do it with zombie panic. Let me know if you get any mods working.

Lol, I gave up trying. Steam makes everything so complicated!
