Yes it is region free
Imo nothing compares to CoD2 vet. To show how simple it is, I finished the TV station bit on Vet mode without firing a bullet. I'm using the same silly tactics as I used in CoD 2 & 3. Just rush forward and force the checkpoint before the enemy has time to settle into their positions.How hard compared to COD2 on vet - as apart from 2 bits that destroyed part of my sanity, I found that a fairly good balance if I took my time.
Vet mode in the cod series is fun? Well it's hardly challenging is it? Tedious more like with it's repetitive scripted sequences.no fun though^^
