The game entered the beta phase on December 22, 2016, and left Early Access on March 23, 2017. Last update was on the 21st of December, 2017.
Gameplay
Day of Infamy draws a lot of its gameplay from Insurgency. Much like their previous title, Day of Infamy lacks a crosshair, HUD map, and on certain servers, a kill feed. A player will die by being shot once with a rifle, and respawns occur in waves. Each teammate gets a number of Supply Points they can spend on weapons and gear for their soldier, a class in each team to select and a weight system which affects Stamina and player speed. There are nine player classes that a player can choose from. The available classes are:
Each team receives a certain number of reinforcement waves dependent on game mode. Your team gains Supply points by completing map objectives and killing players from the opposite team.
Battles and Casual w/ Bots focus on games with reinforcements and larger player numbers, with up to 32, to 40 players at a time. Special Assignments have 16 player servers, and no reinforcement waves available or limited and special case respawns.
Battles or Casual W/ Bots*
Frontline*
Frontline is a 5 controlpoint based mode, where each team gets an equal amount of reinforcement waves. Each team has an HQ Radio, or the Base control point which can be destroyed. A team wins by wiping out the enemy team or seizing all objectives and destroying the Radio. Teams gain or lose reinforcement waves by completing or losing objectives and the team with the most objectives by the time limit, also wins.
Invasion*
An attack/defense game mode, where the attacking team receives about only 25% of the defender's reinforcements, and has to complete all objectives one by one, finally destroying their radio HQ or just wipe them all out. If attackers reach the radio or HQ objective, defenders will immediately lose all reinforcements. Attackers receive more reinforcements, and defenders slowly lose them, by successfully attacking all objectives.
Offensive
A minor variation on the Invasion game mode, where the defenders have infinite reinforcements and only have to regroup at their spawn to get their dead teammates back. Attackers have regular waves.
Liberation
A number of objectives are neutral and already available, to both teams and are able to be immediately taken in any order. Bonuses are given for taking objectives behind enemy lines. The advancing team gains more reinforcements, and wins by taking and holding all the objectives or by wiping out the enemy team.
Special Assignments
Intel
A capture-the-flag style game mode. The attackers have to take an intel folder from the defenders, while defenders have to stop them.
Firefight
Similar to Liberation, players have to take all objectives or wipe out the enemy team. Players respawn by capturing objectives for their team.
Sabotage
Attackers are to infiltrate, seek out and destroy enemy AA defenses and Fuel depot locations around the defenders. The defenders are to stop them, and win if not all objectives are completed!
Co-op Game Modes
Stronghold
Very similar to Invasion, except the defenders are all bots and attackers have to seize all objectives.
Raid
Fuel depots, enemy officers and AA defenses are all targets and the objectives of the attackers to complete. This is to simulate a special forces type, SAS style raid in World War 2.
Entrenchment
Very similar to Offensive, where Defenders are human players that have to defend against waves of enemies. They retreat to spawn to regroup and respawn all teammates.
