Paste has published some amazing pieces of concept art from The New Colossus, with notes from Art Director Axel Torvenius, to get you excited.
Here are some of the works from the website:
In the resistance hideout, the submarine called Eva’s Hammer, there are many rooms to explore. One of the central ones is the Klub Kreisau, which serves as a common area where you can chill in the bar, play pool, or just talk to resistance members and find out more about the world. This area is in what used to be a giant torpedo silo, but is now completely refurbished into a cozy and chill area
In this game we have a surreal mix. The classic American dream of blue sky and diners, classic American cars and girls walking down the street smiling. But there is something off with this environment. Nazi jetfighters are roaring in the sky overhead, a Nazi parade in the distance and those girls are walking down the street hand in hand with German Officers. Designing a fictional America run by the Nazis has given us some very surreal moments in this game.
The Nazis have perverted many landmarks across America. One of them being the Lincoln Memorial. Turned into a perverse scene for their gruesome actions, the Lincoln Memorial now stands for something completely different. This is a concept showing the enormous brutalist buildings raised around it and the re-built monument itself.
