PlayStation will round out Drake's story by offering Uncharted 4: A Thief's End for free in April. Uncharted 4 is joined by Dirt Rally 2.0, an off-road racing game that released in 2019. Both games will be free to keep as long as you maintain an active PS Plus subscription.

Still available - Shadow of the Colossus & Sonic Forces
Interestingly, SEA (South East Asia) region also gets Monster Hunter World.
Really wish Sony would be more consistent across all regions.
