Check out this stickied thread. It says that (regardless of what game you own), you can play "EF's challenges".

I personally own vCoH and OF, but I don't see or have access to any "challenges". Am I missing something?

There was a challenge map where you would fight against waves of enemies, though it was not very good

But im actually in the progress of re-doing and recoding the challenge map and it looks awesome so far, so you will probably see the challenge map once again in a patch or 2

Can you guys tell us what's the progress on the new patch atm? i mean on a 100 percent scale , around 60 percent i guess?

Around 1~99%. Please be patient. We will inform u as soon as possible about the patch.
