Have you played through the game on PC? There's excellent additional content for the PC version that hasn't been ported to consoles yet.

Specifically, it's a scenario pack which is centered around various characters who are all trying to complete specific objectives during the conflict rather than just focusing ordinary survivors who are trying to scrape by.
Edit: Clarity and grammar.
