Call Of Duty 5 : World At War
It takes place at the Reichstag, the place of the final battle for Berlin, so therefore has the Eastern Front setting. It has the outdoor "ruined city" setting, similar to Upheaval's. It has a few high up sniping positions, but mostly in the level it is hard to find an effective sniping position. This level also has 4 tanks in it, 2 T-34s and 2 Panzer 4s.
defeat the tanks by infantry (Bazookas/Satchel Charges are recommended). Try to get teammates to all ambush or attack a tank from all sides. At least 2-3 players wielding Bazookas or a good Satchel Charge placer should be able to kill a tank in one raid. Gang up on the enemy tanks and make sure they do not try to steal them again.
There is a underground part near the end which has a grate for a roof so it is easy to shoot up and kill people who are unaware, the minority of players know about this so it is possible to get a group of friends and ambush the opposition. Grenades can be thrown up through the grate but not down. However, the bunker is isolated so it is unlikely there will be much action.
