Sackboy: A Big Adventure

The Platinum is fully offline, but several trophies require local couch co-op with two controllers.

PS5, PS4 Two controllers required for co-op trophies

Reason

Although the game features roughly a dozen multiplayer-tagged trophies, every single one supports local couch co-op. Zero online connectivity or PlayStation Plus subscriptions are required.

Two Controllers Required: You will need a second controller to turn on a second local Sackperson. You can either play through the co-op requirements with a friend in your living room or control the second Sackperson yourself.
Local Co-Op Trophies: All interaction-based trophies, such as high-fiving, Up high!, slapping each other, Slap Attack, starting a dance party, Let’s twist again…, or carrying the second player through a Knitted Knight Trial, Beast of Burden, unlock in local split-screen.
Teamwork Levels: The mandatory Teamwork levels, required for 100% completion, can be launched and cleared locally using two controllers.
No Online Server Dependencies: The game tracks all level scores, stickers, costumes, and level Ace completions locally on your console.
