Call of Duty: Modern Warfare 2 Highrise remake by @BroomyGraphics. Features a platform for bolt action, handcannon and pump shotgun.

"Welcome to my first map which is Highrise, this map has been my pride and joy. The inside of the buildings have been furnishing to be pretty close to the actual map design whilst working with what I had. Sadly I don't have the helicopter on this remake because I just wasn't sure how I could remake the vehicle. Regardless, I hope you enjoy it never the less.
Both of these maps will have a small platform off to the side which provide chests to get Purple Bolt, Gold Deagles and Gold Pump Shotgun to add some variety to your Free-For-Alls. Just make sure to start the minigame, make your way to the platform and grab your weapon. Once you are ready, head back onto the main map and duke it out."-ItsJustBroomy
