Original: Instead of having each player be an identical Spartan as in previous Halo games , the first player plays as Master Chief , the second player plays as the Arbiter and the other two players control two other Elites ; N'tho ` Sraom and Usze ` Taham , each with their own backstories .
Simplified: The first player takes control of Master Chief , the second player plays as the leader of the Elites , Arbiter and the last two as elites themselves .
