F_20
SteamThe events of the game take place during the First World War. The main character is a soldier of the British Expeditionary Force fighting in northern France, who becomes a victim of a cunning plan and tries to escape a series of inexplicable events, attempting to understand what is really happening and to separate truth from lies. The protagonist must figure out how to survive in a game where he is merely a tool and peel back the veil of mystery surrounding what is actually going on. Meanwhile, the fate of the main character depends on the player's choices.

F-20 Eclipse is a midcore game focused on realism to deliver maximum immersion. You play as a soldier of the British Expeditionary Force, choosing one of three main specializations: assault trooper, machine gunner, or sniper. Each role defines your equipment and the way you approach missions.
Specializations offer unique tasks and routes, providing diverse gameplay experiences. The locations and gameplay are tailored to different playstyles — from CQB and mid-range firefights to sniping, stealth runs, and battles against the horrors of darkness.
The weapon system in F-20 Eclipse is meticulously crafted to ensure absolute authenticity. Each weapon is a faithful recreation of its real-world counterpart, including serial numbers, manufacturer emblems, and production dates. This level of detail lets you truly "feel" the weapons as if you were holding the originals.
Realistic weight, recoil, reliability, and handling influence gameplay. For example:
The attention to realism extends beyond weapons. The equipment and uniforms of the soldiers are painstakingly recreated using archival records, reenactor references, online sources, and historical documentation. Even the chevrons and unit emblems precisely match those of the actual units that fought in World War I. The appearance of the soldiers authentically reflects the era, immersing you in the true atmosphere of the Great War.




The main characters of F-20 Eclipse are based on real soldiers who actively participate in combat operations. These individuals not only serve as actors for the game but also as consultants on military tactics and combat scenarios, ensuring authenticity in every detail.
The character designs are crafted using real-life references from archives, historical photographs, and expert consultations with reenactors, historians, and military professionals. This meticulous attention to detail ensures that the characters are not just visually accurate but also authentically represent the soldiers of the era, bringing the harsh realities of the First World War to life.



The world of F-20 Eclipse is a carefully crafted combination of open landscapes and diverse indoor environments, each designed to immerse players in the grim and haunting reality of World War I.
Set in northern France, where British forces fought during the war, the game’s locations are brought to life using real-world references. Some areas have been meticulously reconstructed based on historical records and on-site research, offering an authentic glimpse into the past.

Open locations span vast battlefields of up to 5 square kilometers, allowing players to experience the varied theaters of war. From the endless trench lines of positional warfare and artillery-ravaged villages to the desolate outskirts of the Somme, these environments vividly portray the harsh realities of combat.

Indoor locations present a stark contrast, plunging players into claustrophobic tunnels, fortified bunkers, and sprawling closed spaces like field hospitals. Each setting is designed not only to reflect historical accuracy but also to evoke the tense, oppressive mood of survival and combat.

The diverse environments in F-20 Eclipse challenge players to adapt their strategies and
immerse themselves in a world shaped by war, destruction, and the enduring human spirit.
