I've been working on this map for a few years now (the idea for the map is atleast 5 years old, the first prop was made like 2-3 years ago, and im not using any CSGO stock content!) I put it up on workshop a few weeks back. It's still in beta but it has come along way.
About the map:
The spawn areas are separated from the main play area. T is going to spawn in a basement/garage place (in this beta they spawn in a black void) where they are gearing up and planning their coup. CT will spawn in a police hangar/dock/garage area from where they get to choose one of four vehicles which represent different INSERTION points on the map. Then they have to rescue the hostage, whom is being held in the big red house, and escort him to one of the four insertion points.
