[5][6] The final update for the game was released on December 21, 2017, after which official support and community modding efforts died down.
There are nine classes players can choose from: Rifleman, Assault, Support, Flamethrower, Engineer, Machinegunner, Sniper, Radioman, and Officer.
Each class has mostly unique armaments, equipment, and attachments to suit their roles, such as long-range scopes for Sniper, submachine guns for Assault, or deployable ammunition packs for Support.
The Officer and Radioman classes are designed to work together to request fire support, a teamwork-oriented feature introduced in this game where the Officer can request special assistance such as artillery, aircraft strafes, or dive bomber strikes.
Day of Infamy began as a free mod developed for their previous title, Insurgency.
