Oldrich Street, Colorado

Gentlemen, we have an emergency call. We have just received a report of terrorists who have taken over the top floor of the penthouse, where they have planted a powerful explosive, as well as a machine gun on the balcony, from where they sometimes shoot at civilians. We don't know much about the number of enemies and their tactics, but we should expect plenty of fortifications made of shoot-through elements and an attempt to hold you off before the device detonates. They also have at least two hostages, so it's possible they'll try to eliminate them. Your main task is to defuse the bomb as quickly as possible, after that eliminate all remaining terrorists. Good luck with that. And don't forget there's an elevator in the building, okay?
