Quotes
"Corpus has been in contact with Kane's forces all along. Their air assault was intended only to pave the way for Kane's ground forces. To fight this threat, Special Forces may not be enough. It's time to call in an old ally that owes us a favor..."

- Event Message #1

"Kara has contacted her Survivor allies for support against the combined threat of Kane and Corpus. The Survivors have been working hard to build a military force after we freed them from the Sentinels and, after a year of seclusion, they're ready to join the fight."

- Event Message #2

"The Liberators are the core infantry unit of the Survivors and they bring with them massive firepower. Together, we just might be able to force Kane and his hordes out of our Sector."

- Event Message #3

"Commander, help! Zombies are back! - They're all around us, there's too many, we need you! Use fire! Reinforcements incoming! - Luckily, we've got a ton of new units for you to crush some skulls, get in here!"

- Event Message #4

"The fight is not as decisive as we would have hoped, Commander. We have to win this war!"

- Event Message #5

"Most of Kane's forces have retreated, Commander, but it is not clear why. This does not feel like a victory, it feels like the calm before the storm..."
