About Second Extinction™

✦ AI summary

Team up with up to two friends to mow down mutated dinosaurs across a dynamic map where community efforts directly impact the threat level of each region week to week. Second Extinction is a squad-focused co-op shooter where your collective victories matter—neglect a region and face devastating Emergence Events, making global progress a shared responsibility rather than just individual runs.

The goal is simple: Reclaim earth.
In Second Extinction you take on hordes of mutated dinosaurs with up to two friends. Solo players beware: Second Extinction is designed with squads in mind. Only the strong will survive.

The goal of Early Access is also simple: Work with our community to make the
best game possible.
We want to hear your feedback loud and clear, and we intend for our community
to be a vital part of the development process.
Even so, there’s plenty to get your teeth (and claws) into from day one: 6 heroes,
11 weapons (with 5 upgrade tiers each) and 6 missions - plus some special side quests - across multiple regions of our big map.

Our mantra is that players win battles, communities win wars. Nowhere is this
more true than our War Effort feature.
Each region of our big map has a unique threat level. This threat level can be
lowered if enough of our players are successful in their missions and activities. But the dinosaurs aren’t resting either, and they’ll focus their efforts where you aren’t.
Each week the community will see the fruits of their labours or feel the
consequence of their incompetence. Let the threat level get out of control and
you can expect an especially tough Emergence Event to be waiting for you.

By playing Second Extinction you’re not just picking up another co-op shooter.
You’re joining us on a journey as we shape the experience. Every piece of feedback and every mission you play matters. So what are you waiting for? The fight to reclaim earth starts here.

This one still stings as I was actually enjoying it but since the servers shut down and development stopped on this game it gets a Negative review, might not do much but man this was one of those games I was having fun with and put a decent amount of time in though with no way to play it offline from the devs I will have to look for other means of enjoying it maybe. I enjoyed Helldivers 2 and this game was gonna be something like that but failed to do so and missed a great opportunity.

an amazing game!, was really fun for the time i spend on it, sadly, and i need to write this in caps because there are way to many sad individuals out there who cant even ask google the question "why was second extinction's developement stopped" THEY RAND OUT OF RESOURCES AND MONEY https://www.secondextinctiongame.com/news/a-final-update-on-second-extinction i would still recommend this, its amazing, if you somehow can get this working on a lan, or of theres some modders out there who got it working, its worth the effort! as for the angry kiddos out there, touch grass, and stop claiming things that just arent true, you arent cool

Recommended May 18, 2026
