The first in the series to feature a modern theatre, "Call of Duty 4: Modern Warfare" is a military-based shooter game based on modern weapons and conditions. Unlike previous "Call of Duty" titles where the games were split into multiple story sequences, "Call of Duty 4" is based completely on a single storyline involving terrorists and nuclear weapons.
