XCOM 2

XCOM 2 is a turn-based tactics video game. Taking place 20 years after the events of Enemy Unknown, it follows the continuity that XCOM, a military organization trying to fight off an alien invasion, has lost the war, and is now a resistance force against their occupation of Earth.

As with previous games in the series, XCOM 2 casts the player as the commander of the eponymous military organization, now reduced to a resistance force opposing the ongoing alien occupation of the planet. Players take control of the Avenger, the new mobile base for XCOM. Players are tasked to give commands to squad members in battles against aliens during missions, while commanding the engineering and research department of the base between missions to create and research improved and new gadgets, weapons and technologies to assist players in battle. Soldiers can be recruited, with each soldier class having their own skill trees and abilities. For example, the Grenadier class can gain access to explosives and grenade launchers, while the Ranger is equipped with melee weapons like swords. Armor and weaponry can also be researched and upgraded by the player in the Avenger base. Each mission’s environment is influenced by the world’s state, while maps are procedurally-generated to create a wide variety of levels, in which every map features different terrain and buildings in each play-through. Mods are also supported. Campaign, class and enemy types can be created by users and can be shared through Steam Workshop. A one-versus-one multiplayer mode also returns from Enemy Unknown. New enemies are also featured, such as units from the new faction, ADVENT, and more alien types like the Viper
