Alright so I believe this IS better than COD:4.
But I love WW2 games. This is by gar the best WW2 game out there and I will say the levels remind me of a Gears of War feeling to them - they're huge with beautiful scenery. The maps for MP are huge and allow for every class to get what they want. Plus, with no laser sight, I thought it would be worse but it is surprisingly challenging and fun at the same time...
I think it is more intense than COD:4 as well. I feel the dogs are more fun than the helicopters as well.
All in all, if you enjoyed COD:4 - you will enjoy this
