Gameplay

Weapons and upgrades are available, with interchangeable upgrades between weapons such as adding the barrel of one assault rifle to another. The "pimped" option returns along with new camouflage schemes. Weapons can now also be obtained from dead enemies, increasing the player's arsenal to four weapons, along with grenades. Bullets will be able to penetrate weaker materials such as wood and sheet metal. Certain weapons and weapon lockers can only be unlocked by morality moments. Weapon parts can be obtained in the game for free, either by searching armored boxes (which are locked as soon as the enemy guarding it detects the player's presence), rescuing hostages, or simply exploring.

New Heavy enemy types appear as bosses. They wear thick armor and often require a special method of attack to defeat, such as shooting gas canisters or grenade bags that they carry. The Heavy enemies carry weapons such as a flamethrower and a Gatling gun that cannot be unlocked by the player, though they can be picked up and temporarily used after the Heavy is defeated.

Co-op playbook

The 40th Day expands on and refines the cooperative play featured in the original game. Players can use co-op moves at any time. The playbook allows players to scan enemies prior to engaging them in order to set up particular team-based tactics. For example, players can mock surrender or set up simultaneous sniper shots. This is in addition to using aggro as a mechanic for tactically engaging enemies in the midst of combat.

Aggro

Aggro is a system that allows two players to tactically control the target of their enemy's attacks and possibly change the outcome of a firefight. Aggro is measured by a HUD element that displays which player the enemy characters are currently focusing on. By performing aggressive actions, such as firing one's weapon at enemies, a player generates aggro and in turn causes enemies to focus more of their attention on that player, and less attention on the player with less aggro. While one player has aggro, the other is usually being ignored and as a result, can then freely perform actions such as flanking or sniping. In The 40th Day, additional non-aggressive actions can affect aggro. For example, by performing a mock surrender the enemy combatants will focus all of their attention on the player that is surrendering, allowing the other to perform a surprise attack. Some non-aggressive acts can be performed cooperatively as well.

Morality moments

In The 40th Day players are forced to make moral decisions that affect the story of the game. At pre-determined points in the game, players will be presented with a choice. For example, whether they should steal weapons from a mall security armory or vacate the premises. The decision is not a vote between two players, but instead either player must decide while the other player is forced to accept the ramifications of that decisions regardless of what their preference was. The outcome and presentation of these morality moments takes the form of comic panels created by the popular artists Chris Bachalo, Jamie Mendoza and Jock.

Multiplayer

Multiplayer in The 40th Day includes region-free play, client-server connections, and an increased number of participants.

The 40th Day maintains its focus on cooperative gameplay by requiring that players play in a partnership. Partners are a source for ammunition and are able to revive their fallen teammate. There are four multiplayer game modes: Co-op Deathmatch pits teams of two against other partnerships. Control awards points to teams for capturing and defending randomly spawned points. Warzone has players battle over various objectives. Extraction is a game mode where teams of four fight waves of increasingly powerful enemies in order to clear the map for extraction.
