Friends of Duty is an action multiplayer shooter built for PC that recreates the feel of early Call of Duty games while adding modern technical features. It focuses on small-scale matches with friends, using movement and damage models drawn directly from the originals. The game runs on a current engine and supports controller play through Steam Input, including full customization and 4K output on Steam Deck.
Gameplay
Matches take place on 26 maps that support a full day-night cycle. Play begins in morning light and progresses through changing conditions until night falls. At night the maps become genuinely dark, with only starlight and minimal moonlight for visibility. Footsteps carry farther in low light, and muzzle flashes reveal positions across the entire map. Players can choose to move quietly or hold positions until dawn returns.
Every player and object casts real-time shadows that shift with the sun angle. A rooftop position that offers concealment at noon can expose a silhouette on a ceiling inside a building later in the day. Cover value changes continuously rather than remaining fixed. The 19 firearms plus grenades, smoke, and the Panzerfaust use ballistics that match the original games, including penetration, damage falloff, and hit zones.
Two presentation options exist side by side. Classic Mode preserves the original pacing and visual style without alterations. Next-Gen Mode applies updated scope rendering with depth of field and refined optics while leaving the underlying movement and damage unchanged. Both options share the same maps, weapons, and rules.
Game Modes
Classic Mode delivers the unaltered experience players remember from the source titles. Matches follow the same pacing and rules as the originals, with no added mechanics. Next-Gen Mode applies the same ruleset but renders it with modern display features suitable for current hardware. Players select either option when creating or joining a match.
Matches support configurable settings for map rotation, kill limits, time limits, and time-of-day progression. Dedicated server support allows groups to maintain persistent instances. Steam lobbies handle invites and allow friends to join ongoing matches without additional setup.
Technical Requirements and Setup
The game requires ownership of Call of Duty 1 and United Offensive on Steam. An included exporter tool extracts the necessary assets from a player's installed copies to create a personal content package. The process uses Blender 4.2 or later along with Python and runs automatically once the tools are present. Each player must generate their own package from legally owned copies; sharing generated files is not permitted.
Native Steam integration handles lobbies, invites, and drop-in play. No port forwarding or external server configuration is needed for standard use. The title supports up to four local players on one machine through controller customization.
Is It Worth Playing?
Friends of Duty suits players who want the original multiplayer feel with updated lighting and shadow systems. It appeals to groups that already own the source games and prefer couch-style sessions over large-scale modern shooters. The day-night cycle and dynamic shadows introduce new tactical considerations without changing core movement or weapon behavior. Those comfortable with the technical export step and seeking a faithful recreation with modern conveniences will find the experience matches the described intent. Players looking for entirely new content or traditional free-to-play progression should note the requirement for the original titles.
