It builds off the atmosphere and nostalgia of this classic experience , but adds more visceral and intense core infantry mechanics . ofnewworldsgamesThe initial goal of the project was to become a continuation of the Day of Defeat experience established by the HalfLife mod team in 2001 . Applying Insurgency ' s popular infantry mechanics and building in this inspiration made up the initial release of what would become a popular total conversion mod for Insurgency . We always said from the very beginning there ' s a chance Day of Infamy would become commercialized , however we were not sure whether we actually had permission to make the game as an openly spiritual successor to Day of Defeat . We were concerned that Valve would not be fond of us commercializing a game inspired on their IP . After the mod version of Day of Infamy launched , we reached out to Valve to get their thoughts on the project . The original DoD creators checked it out and gave us their thumbs up . Valve offered to license Source Engine again to us so we could make the DoDinspired game .
