In the following Call of Duty games, players have to reach a checkpoint to save their progress. The other unique feature is that players could save at any point throughout the campaign, regardless of where they were. One of them is that you do not regenerate health, and have to manually heal with a first-aid kit found on the map.
There are two key features to Call of Duty that are not in the other Call of Duty games. Each mission has a series of objectives that must be completed before moving on to the next mission. The game varied from other shooter games such as Medal of Honor because the character in-game worked with others to complete the missions, rather than acting as a lone wolf.Ĭall of Duty has three parts to its campaign, where you can play as an American soldier, British soldier, and a Soviet soldier, trying to defeat the Axis powers. This game was a new type of single-player shooter, where the person playing controls a soldier within a unit, completing various missions in the setting of World War 2. The original Call of Duty game was released in 2003 and made by Infinity Ward.
