For full historical accuracy there will be two campaigns: a Nationalist and Communist campaign.
Nationalist campaign, you fight the far superior Japanese war machine and hold on against insurmountable odds, even as your countrymen are butchered.
Communist campaign, you hide in the mountains with Mao, wait for the war to end, then attack the exhausted Nationalists.
