Act of Aggression is a real-time strategy game developed by Eugen Systems and published by Focus Home Interactive. It was released on September 2, 2015. Act of Aggression is stated to be a spiritual successor to Eugen Systems' previous Act of War titles.
The game aims to "bring the players back in the 90’s Golden Age of strategy games", implying that Act of Aggression will be a traditional RTS, with its gameplay similar to Command & Conquer and StarCraft. Act of Aggression will thus include base building and resource management. There are to be multiple resources each faction relies on to sustain their game economies and to build their forces: deposits of aluminium, petroleum, electricity, and rare earth elements are scattered across the map. Banks and prisoners of war can be captured for a supplementary source of income.
The game will include superweapons and "anti-superweapons" for each of the factions. Each faction will upgrade in a centralized headquarters in order to unlock new units, buildings, and upgrades. Skills and abilities for units can be unlocked to specialize them in roles, such as anti-air, anti-tank, etc. Act of Aggression will have an in-game day and night cycle.
There can be up to 40 players in a multi-player match.
Act of Aggression is to be set in the 2020s, during which many sovereign states around the world have gone bankrupt from a massive economic crisis. This results in the growth of an organization known as the "Cartel", a shadowy group of operatives born out of private military contractors that has infiltrated numerous government organizations and agencies, taking power from the United States and the United Nations. This forces the United Nations to militarily respond.
Act of Aggression will include two separate single player campaigns. In one of the campaigns, players will be a head of a multinational military organization created by the United Nations, known as the "Chimera". The Chimera task force consists of super soldiers and are under UNO command, formed by personnel that come from different countries of the UN. The main campaign will also follow the US’s efforts to rout the Cartel.
