| Dobermann | They're still organizing attacks... What a pain. |
| Amiya | Doctor, the path at the bottom of map is now open. Please deploy one Vanguard Operator at the top and bottom paths to hold off enemy Hounds. |
| “ | The cruelty that Reunion displays chills the hearts of the operators. However, no matter what Reunion seeks to accomplish by stirring chaos right before a Catastrophe, evacuation takes immediate priority. | ” |

| Dobermann | Ugh... Gahh... Those sick bastards! I can't believe they, they... |
| Guard | Those beasts... Were they Reunion's doing...? |
| Amiya | Reunion enslaved infected beasts to use as troops... |
| Dobermann | No, it's not that simple. I can feel it, they... Are no mere beasts. In fact, they're more like us... |
| Guard | Instructor Dobermann... |
| Dobermann | ... |
| Guard | Boss... What should we do? |
| Ace | Give them a merciful end. |
| Guard | Boss... |

| Ace | Dobermann, the battle is over. We also had to face off against Reunion forces. The Catastrophe is already looming over us. It's likely to break at any moment. Even Chernobog will be reduced to rubble under its direct impact. |
| Amiya | Reunion is taking advantage of this to sow even more chaos. |
| Ace | Dobermann, we're out of time. We might be able to outmaneuver Reunion or stay concealed from Ursus, but we're powerless in the face of a Catastrophe. |
| Dobermann | ... That's enough. Let's go. No matter how reckless Reunion's plans are, the most important thing for us... |
| Amiya | ...is everyone's safety. |
| Dobermann | That's right. |
| Amiya | Reunion's leaders may see this event as a sign, or even as a means... But for me, it signifies that we will be in greater danger from now on. |
| Ace | Choosing a time like this to incite chaos... Reunion is either insane, or just evil. |
| Dobermann | Perhaps, a bit of both. |
