Steph: I have recently finished reading Halo, Contact Harvest.
It does not make much senswe tho about what you are saying,
I'm saying that since Sgt. Johnson, and the brutes were on Harvest around the time Halo Wars takes place, its possible they could make an appearance. Johnson could be in cutscenes or some special unit in campaign,
The brutes, units in the covenant, or just units that are in certain missions in the campaign.
Never draw fire; it irritates everyone around you.
For every action, there is an equal and opposite criticism.
