ArmA has a zombie mod too.

I'll let it speak for itself, for the most part.

The cool thing about ArmA is that you have huge islands with many towns and places to go... so there's a lot of freedom. And there's an easy-to-use editor where you can put down cars, jeeps, tanks in towns as well as weapons. Or AI, if you want. Oh, and there's multiplayer.

I played OPFP, and I heard of ArmA once.

What's new/different?

Well, it's a graphic update for the most part. But they also changed the islands so it's quite a lot bigger, and modernized the weapons and vehicles. And the multiplayer is a lot easier to get working than Operation Flashpoint's. You can join mid-game, for example.

There is a multiplayer demo on the 'net. The co-op mission is nearly impossible to beat, but I have done it with some amazing commanding skillZ. (I.E. AI micromanagement, hardcore. Hold the church on the hill and equip everyone with a machinegun.)

Unfortunately, no zombies are in the demo, but if you've played with the Flashpoint zombie mods then you know what it's like.
