The third game in the series, Call of Duty 3, counts among the less remarkable entries in the series.

The game was released for Windows and for the Xbox 360, and it played a big part in the initial success of Microsoft’s second console. However, the graphics were significantly improved compared to the original. Like its predecessor, it featured three separate single-player campaigns, and apart from the regenerating health, the fundamentals of the gameplay were not changed much. This new mechanic encouraged a riskier, faster-paced playstyle, as opposed to many other games that still featured health bars or health counters. The most prominent one was automatic health regeneration, something that would become a staple of many modern games.

Finally, an improved version named Call of Duty Classic was released on the PlayStation 3 and Xbox 360 in 2009. It also received an expansion titled Call of Duty: United Offensive in 2004, which focused mostly on multiplayer features. In contrast to the sci-fi/fantasy-inspired worlds of many FPS games of that time, Call of Duty opted for a grittier World War II setting, putting the player in the shoes of three different soldiers throughout three single-player campaigns - an American, a British and a Soviet one.Ĭall of Duty was developed primarily for Windows but was also ported to OS X several months after its initial release. Mechanics aside, the setting itself was more realistic, too. Namely, it limited the player’s arsenal to only two weapons, removed all pickups aside from health and ammo, and it made the player less mobile, as well as more vulnerable to damage. The original Call of Duty was quite different from other first-person shooters of its time, mainly because it was grounded in a more realistic setting and featured more realistic gameplay mechanics.
