Gameplay
As with the original Army of Two, and as the name of the series implies, gameplay in Army of Two: The 40th Day revolves around co-op combat tactics necessary to survive specific and general combat situations. Players can team up with an AI companion in single player mode or a human friend in two-player co-op. Co-op tactics are made aware to the player in what is known as the co-op playbook. Unlike the original game, which in some instances limited the use of some tactics to certain situations, in The 40th Day, players have access to all tactics. Implementing these against opponents revolves around the game's "Aggro" system, tallied in the heads-up-display (HUD) and which measures the amount of attention a team member draws from opponents for certain tactics, leaving the other team member in various states of freedom to launch coordinated attacks as chosen. In addition to this change, players are also faced with moral dilemmas in the game, including choices presented to one of the players on a team that the other must bear the consequences of, as well as the decision as to deal with and/or defend civilian non-player characters (NPCs), who can be killed in the game.

Multiplayer Modes
In addition to its single player campaign, Army of Two: The 40th Day offers a robust, region-free, multiplayer experience that provides an array of unique features for up to 12 players at a time. This experience consists of four modes, including, three brand-new modes that provide a variety of objectives for partners to battle over. The four modes are:

• Co-op Deathmatch - An intense battle of survival between up to six two-player partnerships. Only by mastering teamwork and partnership skills will players earn the most points and come out on top.
• Control - Sets players partnerships as TWO or FDI rival faction members as they aim to capture strategic locations in the city. Work with your partner and faction to control the most points within the time limit.
• Warzone - Is an all-out objective-based battle between TWO and FDI forces. Complete the most Destruction, Assassination, VIP, and Infiltration missions with your partner and faction to crush the opposition and win.
• Extraction - Pits a team of four players against a series of unique enemy waves as they move from point to point in the ruined city. Players must strategize as a unified team to combat the different forces of the 40th Day Initiative while trying to get out alive. Extraction is a bonus mode that will be available for free one month after Army of Two: The 40th Day is released, or at launch for players who pre-ordered.
