This main game, a 2005 first-person shooter, immerses you in intense World War II combat across American, British, and Soviet campaigns. The core loop involves objective-based missions featuring large-scale, chaotic frontline action. Distinctive features include the introduction of regenerating health, requiring players to seek cover to recover, and enhanced enemy AI for more dynamic battlefield encounters. It was released for PC, Mac, and Xbox 360, and includes multiplayer modes alongside three DLC packages.
The game places a strong emphasis on realistic, large-scale combat simulation within the World War II setting. Players engage in frontline action across various fronts of the war. The atmosphere is characterized by intense firefights, large troop movements, and the constant pressure of survival in a massive military conflict.
The primary gameplay loop involves moving through objective-based missions, utilizing period-accurate weaponry, and coordinating with allied forces during pivotal battles. The experience is designed to be visceral, focusing on the immediate action of the battlefield.
A significant mechanical innovation introduced here was the implementation of regenerating health. Instead of relying solely on static health packs scattered throughout the environment, players must seek cover and survive incoming fire for a period to recover their vitality, adding a layer of tactical decision-making to moment-to-moment combat.
Furthermore, the game featured enhanced enemy Artificial Intelligence (AI) compared to previous entries, leading to more dynamic and unpredictable enemy behavior on the battlefield, forcing players to constantly adapt their approach to engagements.
This title was released for the PC (Microsoft Windows), Mac, and the Xbox 360 console. Beyond the main game content, there are three downloadable content (DLC) packages available that expand the multiplayer offerings and introduce new maps and challenges.
The single-player component is structured around four distinct campaigns that weave together three separate soldier stories. Each narrative thread follows a soldier as they face insurmountable challenges inherent to the global war effort.

In the mobile version of Call of Duty 2, you take the roles of various soldiers fighting through World War II. There's four years (1942-1945), each one with two soldiers to choose from, each with their own set of missions. Everything but the first missions are locked, and you have to complete them to unlock the later ones, eventually unlocking the next year as soon as you finish every mission in the earlier one. The missions can vary wildly, from location to objective and weapons. In some missions you have a team of soldiers to help you out, in others you have to work solo. You'll be instructed along the mission on what to do, as well as receiving hints and tips on how to do it. You may have to take down enemy troops, call in airstrikes, hide from bomber attacks, destroy enemy vehicles or even be left all alone sniping enemy units. The time you take to beat the mission is stored so you can try to beat the default "best time" or your own best time. The game works in a pseudo top-down view, since the game works like a 2D top-down but the scenario is rather 3D. Most of the maps are similar, having you start on the bottom and having to make your way up to the top to progress through the mission. You can crawl under sandbags or hide behind buildings for cover, and sometimes there's medics spread around to assist you. The weapons are varied, from pistols, machine guns, sniper, bazooka or even a walkie-talkie to call in airstrikes. Most of the weapons simply fire forward, but to help you aim, some can "auto-point" at nearby targets, and others have a reticule that you move around with the D-Pad.
