In a tweet Arkane Lyon announces a delay to DEATHLOOP, saying this first-person action game is delayed. This didn't carry an exact release date when it was announced at E3 2019, but now they say the new release window of Q2 2021 is a setback:
We've made the decision to move the launch date of DEATHLOOP to Q2 2021.

How are ambition for DEATHLOOP is to deliver a signature Arkane game that takes you to never-before-seen places in a stylish new world.

At the same time, the health and safety of everyone at Arkane Leon remains our top priority. As we've adjusted to work from home, we found that delivering this new and exciting experience, at the polish and quality level that defines both an Arkane game and a true next-gen experience, is taking longer than normal.

This extra time will allow our team to bring DEATHLOOP's world to life with as much character and fun as you've come to expect from our team.

While we know this is the right decision for DEATHLOOP, we share your disappointment, and apologize for making you wait even longer.

Thank you for your support and excitement. Your positive feedback has helped fuel us as we continue to work from the confines of our homes. We can't wait to share more details about DEATHLOOP with you, so keep your eyes open for our next update, coming soon.
