The player has two primary weapon slots, a handgun slot and can carry up to ten grenades. Weapons may be exchanged with those found on the battlefield dropped by dead soldiers. Unlike later Call of Duty games, the first allows the player to toggle between different firing modes (single shot or automatic fire). Call of Duty was one of the early first-person shooters to feature iron sights in game play; by pressing the corresponding key the player aims down the actual sights on the gun for increased accuracy. In addition to weapons carried by the player, mounted machine guns and other fixed weapon emplacements are controllable by the player.
Call of Duty®: WWII creates the definitive World War II next generation experience across three different game modes: Campaign, Multiplayer, and Co-Operative. Featuring stunning visuals, the Campaign transports players to the European theater as they engage in an all-new Call of Duty® story set in iconic World War II battles. Multiplayer marks a return to original, boots-on-the ground Call of Duty gameplay. Authentic weapons and traditional run-and-gun action immerse you in a vast array of World War II–themed locations. The Co-Operative mode unleashes a new and original story in a standalone game experience full of unexpected, adrenaline-pumping moments.
For instance, in one map the attacking team has to take an enemy outpost in the first stage; in the second, the attacking team needs to build a bridge across a shallow gorge; in the third they need to plant a bomb on an ammo depot and make sure it explodes; and finally they need to guide a tank to the finish line. Across all these stages, the enemy team is required to stop them. For the attackers to win they need to complete each stage. For the defenders to win they simply need to stop the attackers at any point. Each stage has a timer.
On November 5, 2010, EASY Studios announced a follow-up to its free-to-play Battlefield Heroes, Battlefield Play4Free. EASY develops the free-to-play variants of Battlefield. Its latest offering gives players the same free-to-play pricing structure of Heroes, while still offering a more serious, core Battlefield experience (as opposed to Heroes' lighthearted, cartoon-styled environment). Battlefield Play4Free went into open beta on April 4, 2011.
