Call of Duty 2 - is a first-person shooter that has a single-player story
mode and a multiplayer mode. The player takes on the roles of several
Allied protagonists in specific missions during World War II. The player
can crouch and lie prone, and is able to scale low walls and other
obstacles. Two firearms can be carried, which can be swapped with those
left on the battlefield, and both fragmentation and smoke grenades can
also be carried. A gun's iron sights can be used to aim more accurately.
A compass on the heads-up display
(HUD) shows both allies and enemies, and objective markers to indicate
locations the player must reach, areas to defend, or enemy cannons or
tanks that the player must plant explosives on to disable. Emplaced
weapons such as machine guns and flak cannons are available in some
locations to take out enemy forces. In addition, some missions place the
player in control of a tank.
The player has a set of binoculars. While it is generally ignored during
infantry-limited gameplay, it is vital to the long-range use of the 88
millimeter guns, Crusader tanks and one of the missions in which the
player must direct artillery fire to defend a town. It is also important
for scouting, though most of the game takes place in personal, close
combat situations reducing the importance of this tactic.Should the
player take severe damage, the screen will turn red and the sound of the
character's heartbeat will increase in volume; this indicates the
player's health is low. The player must find a way to stay out of fire
to recover before entering battle again or else will die and restart
from the last checkpoint. Health is only restored through automatic
recharging when the player is not taking fire. Some attacks, such as
explosions from grenades or shells, will kill the player instantly if
the player is too close.
In April 2006, Infinity Ward released the Call
of Duty 2 Radiant, which allows a player to create their own
multiplayer or single-player maps. Along with Radiant, the mapmaker
includes Maya plug-in support, an effects editor, and an asset manager
which allows custom models to be made and imported into the game, as
well as custom effects.
