Call of Duty 4 is an action-packed online video slot based on the popular first-person shooter video game. The video game franchise began on Microsoft Windows and expanded to handheld devices and consoles soon after that. Call of Duty 4 is set in modern times and takes place during 2011.

It's only logical that a slot game was soon to follow and those that liked playing the video game series will enjoy the slot game just as much. Developed by Cryptologic, Call of Duty 4 is offered on five war-infused reels with three rows and twenty-five pay lines. The slot is further enhanced with an infusion of bonus features including multiplier symbols, a free spin feature, bonus symbols, scatter symbols, a bonus game, and wild symbols along with a 200 coin jackpot prize.

Themes and symbols

The theme of the slot game is based around the video game plot where a civil war has broken out between the government of Russia and ultranationalists seeking to restore the country to its Soviet-era glamor. The background takes place in an abandoned building on the outskirts of Russia where lethal weapons and explosives have destroyed most of the building. The reels are cleverly placed inside a holographic sight located atop one of your weapons to compliment the theme of the game. Each pay line received a different color coding while the control panel provides a military look and feel, adding to the feel and look of the slot game.

The symbols are portrayed in front of a black background, and all symbols perfectly relate to the theme of the slot and the video game. There is a total of 10 standard symbols including the sight of a gun aiming at an enemy’s head, an AK-47 machine gun with six bullets and a black gas mask with a military helmet. Joining this military theme are a flashbang grenade, a symbol indicating a hand grenade,  target symbol, shield logo, speed enhancement logo in red, C4 logo and an extra magazine logo in blue.

Special Features

The squad of soldiers who are busy shooting at enemies will represent the wild symbol and will substitute for all standard symbols to generate a bigger win. Revealing five soldier symbols on an active line will see you enjoying a win of 5,000 coins and will double your winnings when forming part of a win. The Call of Duty game logo will act as the scatter symbol, paying 200 coins when five appear on a payline, and these will unlock the main feature available in the game.
