I posted a review here earlier this year, but A Way Out was an excellent 2-player co-op game! I really enjoyed it. Story rich puzzles with some action interspersed. And it’s split-screen even if you’re playing online, so you can see what your partner is up to and coordinate with them. The ending was heart-wrenching too! Such an emotionally impacting story. Check out my review for a spoiler-free intro to that game.
