Halo Wars 2 is a real-time strategy game based on the Halo universe and it is the sequel to the 2009 Halo Wars. Players use Spartans, Warthogs and other classic Halo units in order to battle the enemy. A single-player campaign and online multiplayer battles are available.
The game has a single-player campaign with twelve missions that can also be played cooperatively. Typical mission objectives include surviving waves of enemies, defending structures and capturing specific targets. There are also various side objectives. Many missions involve leading Spartan supersoldier units as well.
Halo Wars 2 features two factions: the human faction United Nations Space Command (UNSC) and a new alien faction called the Banished. The Banished replace the Covenant from the first game. Both factions have leader units with special abilities that can be used once every few minutes. These abilities can either heal or deal damage in short bursts.
The game also has multiplayer modes for up to six players online or against bots. This allows players to compete against each other and test their skills.
