Enemy Front is a first-person shooter set during World War II. The player takes control of American war correspondent Robert Hawkins who fought along with resistance fighters in various locations in Europe such as Germany, France and Norway, along with the Warsaw Uprising in Poland. The game starts with an audio broadcast where Hawkins announces he will tell the story of what he has seen and the game is then played as a flashback.
The gameplay involves completing missions while fighting alongside other soldiers. The arsenal includes hand guns, machine guns, assault rifles, and sniper rifles, as well as weapons commonly associated with resistance fighters like the sten gun, welrod pistol, lightning submachine gun, and molotov cocktails. Weapons and ammo are picked up along the way or swapped with those left behind by dead soldiers. A tactical approach is possible through sabotage and stealth, allowing players to silently take soldiers hostage, dispose of them, and drag their bodies away from enemy detection. The game also features a noise indicator, where loud noises like planes flying by offer a time-frame to shoot without being revealed.
The game has a variety of mechanics, including the ability to sneak through foliage for stealth kills, throwing objects like stones to distract enemies, and using binoculars to watch enemy movement from a distance. Hawkins' health status is revealed through visual cues, such as a red glow when injured, which fades automatically when kept low. There are three difficulty levels: casual, normal, and expert, each with its own challenges. The game features multiple sections with primary and secondary objectives, including rescuing hostages, locating officers, stealing supplies, and placing explosives. While the progress is largely linear, players can choose different approaches due to the size of the environment.
Enemy Front supports online multiplayer for up to twelve players simultaneously, adding a new layer of challenge and gameplay to the already engaging experience.
