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.

F you for leaving this game Devs, you should be ASHAMED of yourselves. Ever since the game had a trailer I patiently waited for it to drop; I played for a bit and I RARELY got matches with someone. I am SICK of devs who are NOT making games being able to be played offline.

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

it is a very, very good game... too bad it got drowned out by newer, and bigger titles, and couldn't keep up and had to be taken off of all stores... but hey, the keys for steam still work! so you can still get it :D
