That's the Playground-base from the series Marvel's Agents of S.H.I.E.L.D. The map includes all places of the original underground base as well as some own additions like a separate Quinjet hangar and a leisure area including a football pitch, a park and some other activities. Furthermore, I've added some Redstone and commands for realizing some features like opening the hangar-shots. Some areas of the playground are protected by a key-card-door. If you don't own a key when starting the map, you will find some in the protected storage behind Scie-Tech and the training area, as well as in the flying bus version in a chest near the parking area. You must know, that I built the map with the help of a room plan (you can see in the gallery).

I tried to make the map as real as possible and hope you enjoy playing on.

For better graphics, use the texture pack downloadable together with the map.

PS.
Open the last doors in the director's office as well as the lowest chest to activate a secret escape floor behind the last picture (in the left of the chest). If you go to the lowest level of the observing building on the runway, you'll find a dropper in the wall which opens you an elevator to the Playground-base. Just put the key-card in and press the button.
