Halo Wars is a real-time strategy video game. Halo Wars is the 5th halo out of all the Halo series, but Halo Wars time line was based before all Halo video games. Halo Wars was made by Ensemble Studios and was Published by Microsoft Game Studios.
Personal Opinion: I like Halo Wars because it mixes my two favourite things, My favourite first person shooter game halo and like the idea of make a large UNSC army or a large Covenant army, how cool is that?
