its pilot has learned. Links is a feature that allows multiple units to provide offensive and defensive support to each other during battles. Unlike in Front Mission 2 and Front Mission 3, players have greater control over Links. Up to four units can be linked together to form one "link"; an offensive link for Player Phase battles, and a defensive link for Enemy Phase battles. Additionally, the player can dictate the degree of support a unit can provide; a linked unit can use battle skills or no battle skills at all. For linked actions, a weapon must be set in order to participate in an offensive or defensive linked battle. Lastly, two special actions can also be set as linked actions: Antilock and Salvage from EMP and radio backpacks, respectively. Antilock causes missiles within range to miss, while Salvage restores any wanzers destroyed in battle. Returning features aside, Front Mission 4 has a number of new gameplay mechanics. Weapons are now capable of attacking more than once during any battle, provided that the unit initiating the attack has sufficient AP and weapon ammunition. The time of day affects a weapon's chances of hitting its target; for example, accuracy is lowered during night time. Weather conditions affect the effective range of weapons; for example, a blizzard will reduce a machine gun's maximum firing range by one square. Like in Front Mission Alternative, there are new auxiliary backpacks that offer unique features when used on the battlefield. In addition to the item, turbo, and repair backpacks, players can now use jetpacks, sensor backpacks, EMP backpacks, and radio backpacks. Sensor backpacks are equipped with sonar and radar sensors that extend the firing range of missile launchers. EMP backpacks are armed with electromagnetic pulse (EMP) waves that disable various functions on its target. Jetpacks have built-in verniers that allow a wanzer to scale buildings and directly bypass obstacles such as water. Radio backpacks have communications equipment that allows a wanzer to act as a forward air controller by signaling a transport to drop supplies, armor coating, or call in an air strike. Aside from these new additions, turbo backpacks now come with a small amount of item space and repair backpacks can remove EMP-inflicted status damage. Plot Set in 2096, the story of Front Mission 4 takes place in Venezuela and Europe. Since the revelations of the true causes behind the 2nd Huffman Conflict
