The flags appear directly in front of and behind the Gustav, which makes this game mode more of a fast-paced slug out than most other maps. You can run up and over the Gustav, or go along its sides. If you do go up the side, it’s best to use the eastern side through the Tank Grounds rather than the western side. There’s zero cover on the western side, so if you have the flag, you’ll be little more than target practice for some haute deadeye.
You can also take the long way around the outer rim of the east side of the map for a sneaky flank; or, go between the hills and houses on the west side to the same effect. Whatever you choose, you’re better off making a straight line back to your base, rather than taking the same way you came in. Running up the right side of the Gustav will provide the most cover. You can also climb on top of it, but the path up to the top exposes you to pretty much any enemy who’s looking for you. Once you’re up and over, however, it’ll be smooth sailing back to your flag.
