The hopeful squeal of our beloved Halo Wars.
The campaign portion of the game would be taking place on the Forerunner planet Requiem, after the defeat of the Didact. Around the same time frame as the Spartan ops in Halo 4 are taking place.
Now the multiplayer/skirmish playlists have three different factions you have the option of playing as. The three factions, the UNSC, the Covenant, and the forerunners, all have three different leaders.
The UNSC leaders could be:
Colonel Laskey: Since he’s in charge on the Infinity, Flying vehicles should be his specialty, The Broad Sword being His specialty unit, An orbital MAC blast as his leader special power, and the passive ability to build two buildings at once.
Dr Halsey: Since she created the spartans, her specialty should be infantry. Her specialty unit should be Upgraded Spartans that are stronger than other spartans. Her Leader power attack should be an EMP burst leaving Vehicles and aircraft temporarily Disabled but ground infantry unharmed. Her passive ability is that she can train up to 6 Spartans. (instead of 3 which is the norm.)
Master Chief or Sarah Palmer: Ground vehicles is the specialty, The Mammoth ,an upgraded elephant , is the specialty unit, and a team of 5 Spartans called fire team equipped with Spartan lasers. (not 5 separate Spartans but 1 unit) The leader ability should be napalm strike that scortches the ground for a long period of time, burning any enemy that walks through it.
Im not so sure about the Covenant or the forerunner leaders yet
