Tense and still good
Even though it is old by now, it still holds up just fine. The graphics are fine and definitely good enough to keep you on the front of your seat when the action heats up.
Stories are so-so, since they are sorta short and broken up. I would have preferred one long campaign, instead of multiple small ones. I can see why they did it though, as you get to experience different armies and settings, from snow covered Stalingrad, to deserts in Africa, over to the traditional french countryside. Maps are varied and quite well designed in my opinion. Large amount of weapons to choose from, and different way to approach each minor battle, and it is clear that they have thought about the design in ways, so you don't have to go the same way each time you try a map.
Gameplay is quite tense when you are doing house-to-house battles (And playing on the higher difficulties) and extremely fun!
So if you are looking for a regular shooter, with a little bit of history served on the side, here's a good game to pick up.
As expected, the game ran perfectly on my 2011 iMac with Radeon 6970M, OSX 10.11.5, and I didn't experience a single bug or crash.
