Flamerthrowers and swimming in Call of Duty: World at War
For the first time you’ll be able to swim in a Call of Duty game in both singleplayer and multiplayer mode. Luckily flamethrowers are back and off course the environments will be completely flammable. According to the developers Call of Duty: Modern at War will be less ‘scripted’ than the previous Call of Duty games. As player you’ll have more freedom in the way you execute a mission.
