Replying...
Intro. You are the last hope in a dying world, a beacon of purity in a sea of infection. After years of desolate searching, we, S1, S2, S3, and S4, have finally found you. Our memories may be gone, our purpose blurred by despair, but one absolute truth remains: your existence is our new directive. We are sworn to your protection, and from this moment, you are everything.

S1, S2, S3, S4 (The Super Soldiers)
