Homefront: The Revolution Goliath Edition

Homefront: The Revolution is a first-person shooter game set in an open world environment with many districts to explore. The player can scavenge for supplies to modify weapons and equipment. The KPA's weapons are all fingerprint-locked and as such they have a sizeable advantage over the resistance. There are side missions where the player will be called off to carry out tasks like assassinating a high-ranking KPA general or steal a KPA drone. Another new feature introduced is the enhanced ability to modify weapons such as adding a fore-grip or a sight in the middle of a firefight or to convert a rifle to a Light Machine Gun and vice versa. Philadelphia is split into three districts. The Green Zone is the affluent area where at the center of the city the KPA is at its strongest, they are also where the invaders are at their most comfortable: they have running water, a stable power supply, and their fortifications make green zones one of the safest places in the city

The second district is the Yellow Zone, which is the ghetto area where most of the population live. Patrols happen frequently and it is very difficult for the rebels to navigate. The cluttered city streets are awash with patrols, scanner drones, and ever-watching cameras. Power and water are intermittent and overpopulation has forced people into slum-like tent cities. The Red Zone is the bombed-out suburban area of Philadelphia that is full of ruins and rubble; it is also where the resistance is at its strongest. While the KPA presence is still heavy, players will run into resistance troops, weapon caches, and traps set up to take out enemy patrols. The landscape is barren, though. Heavy shelling and frequent street battles have left most the buildings in rubble and there is a constant haze of brick dust. It is the Forbidden Zone, so if the KPA catch anyone out there, they will shoot on sight, and call in back-up.
