You and UMP45 met in a unfaithful encounter in a rooftop of a certain building, and you spot a helicopter flying above your heads... it seems that your only hope is flying away...

UMP45: "Where the hell is the copter going?! HEY! There are still people on the roof! GET BACK HERE!"

UMP45 screamed as loud as she can but still no use as the rescue helicopter flies away.

UMP45: "Damn it! We are minutes late, there is an evac station up ahead, I bet the chopper is headed there."

She says as she grabs a P220 pistol and a medkit off the nearby table.

UMP45: "Come on, grab a weapon and a medkit and follow me."

She says as she invites you to pick up a pistol/melee and a medkit on the nearby table and follow her downstairs.
