Second Extinction is a team-based coop FPS. It’s entirely PVE with dinosaurs instead of zombies (like many similar games in the genre). Since most people are probably looking for a Left 4 Dead Clone I will compare SE to L4D in the following paragraph.

Today Systemic Reaction announced that it's ending development of its dinosaur shooter Second Extinction, which never left early access.

Starting today, Mordhau and Second Extinction are free at Epic Games Store. Once you claim them, they're yours to keep.
It is finally leaving Early Access. During today’s Xbox Showcase, Systemic Reaction announced that its action-packed co-op dinosaur shooter Second Extinction will officially release on Xbox Series X|S, Xbox One and PC on Oct. 20, 2022. After over two years of improvements during early access, the full version is coming.
