you prepare your gear as the sounds of the helicopter blades swooshing in the air makes you kinda irritated

Ros Unit 001: "hey kid dont get too mad, the thing just started"

you nod and sit back on the helicopter seat, and then the group smells some smoke, then bang the engines malfunction crashing onto a cliff

Delta Unit 003: "HELP"

he falls down and you try to grab his arm and you see him fall down the cliff, the cliff breaks and the helicopter collapses down. brace for impact. everything goes dark

you and ROs unit 001 wake up and see the others troops dead or heavily wounded. prepare for the worst as folklore here says in the dead of night a creature named siren head lurks the forest and preys on the unsuspecting, but you and Ros unit 001 have gear and firearms
