With just days to go before the launch of action game, we’re now getting a better look than ever at just how large the open-world game’s 400-square mile map is.

Just Cause 3 takes place on the island of Medici. This new video from PlayStation Access takes players on a virtual helicopter ride from one end of the map to the other.

As stated previously, Just Cause 3’s world size is not necessarily larger than Just Cause 2‘s, though it’s supposed to feel more “dense” than its predecessor.

“Just Cause 2 was already enormous,” game director Roland Lesterlin said. “We really wanted to focus now on density and the feel of the world itself. So we didn’t necessarily just have to do increased land mass. But we have certainly gone a lot bigger when it comes to density of the world. And now it’s not just on top of the world–we also have caves and tunnels and all sorts of stuff there, too.”

You can also watch this video to see the game’s first hour of gameplay.

In other Just Cause 3 news, Avalanche recently confirmed that it explored a multiplayer mode for the game, but ultimately decided to keep it a single-player-only experience…for now. In addition, the developer has confirmed that the PS4 edition runs at 1080p while the Xbox One version runs at 900p. You can also watch this new 4K gameplay video that shows the game with “all settings turned to overkill.”

The Just Cause 3 release date is set for December 1 across PC, PS4, and Xbox One. What stands out most to you in this video? Let us know in the comments below.
