Call of Duty: World at War
World at War took the mechanics and ideas of Call of Duty 4: Modern Warfare and brought them back to World War II. At the time it felt like a step backward, since the series had finally escaped WW2, but World at War was a good reminder that it’s still possible to make a fun and interesting game in that familiar setting. The key was an exciting campaign, which supported co-op(!), great multiplayer maps, and some fun ideas. Adding a killstreak that lets you call in a pack of dogs to kill your enemies is genius, and I still remember hearing friends scream when I killed enough people to release the hounds. Maybe not as “important” as Call of Duty 4, but a classic nonetheless. Oh, and it was the first game in the franchise to have a zombies mode, something that has become a fan favorite ever since.
