What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

Second Extinction™ was a cooperative shooter with praised enemy design that players genuinely enjoyed, but it suffered from early access bugs and ultimately failed to gain traction before the developers abandoned it and shut down the servers, leaving players unable to play offline. While some players feel it had real potential and could have rivaled titles like Helldivers 2 with further development, the lack of server support and development means it is currently not available for purchase and cannot be played.

Recommended Aug 12, 2026

pls bring this game back or atleast relist it for people to purchase.

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.

The game is good, but it has several bugs since it's in Early Access. If they didn't abandon it, it would be an amazing game.
