Playdead, the developers of both Limbo and Inside, may have teased its next game again.

At the Game Developer’s Conference this year, Playdead gave out postcards asking developers to join them in working on their new project. The postcard showed a tunnel-like picture, much like the previous teaser.

In a tweet earlier this month, Playdead invited interested developers to its GDC booth, stating that “if you are creative, passionate and looking for a new challenge, please visit us at the GDC’s South Hall, Booth #135.” It was accompanied with the concept art seen below.

Playdead also teased its new game last year in tweet, saying that they “have been working on the next adventure.” This was followed by a picture of what could be an astronaut watching some sort of asteroid. Could this mean their new game might be a space adventure? Time will tell.

Nothing else is known about the upcoming game so far, besides the two images that Playdead has released. Even with this, fans of the studio’s games should be excited, considering what the developers have brought with previous games.
