Oxygen Not Included: The Prehistoric Planet Pack DLC Release Date Announcement!

[JarrettM]

We've got dino-mite news: The Prehistoric Planet Pack DLC comes out this Thursday, June 12th! It'll be available on Steam, WeGame, and Epic. 

This DLC is a tribute to everyone who grew up wondering what it'd be like to coexist with dinosaurs... and whether or not they'd survive a dramatic encounter with an impactor asteroid! (It wasn't just us, right?)

Uncover an archaic starting world where cold-blooded Rhexes snack on smaller critters, heavy-footed Lumbs shake ripe crops right off their plants, and gigantic Jawbos lurk deep in fetid wetland pools. Lush fruit vines sprawl over walls and ceilings, while carnivorous flowers lure pesky Gnits to their doom... and produce valuable Amber. Elsewhere on the planetoid, strange plant buds deliver forth farm-supporting pollinator critters. 

Duplicants can lug oversized racks of sinewy dino meat over to the new smoker building to make enough mouth-watering brisket to feed all their friends. They'll need their energy, if they're going to build a surface defense station capable of blasting the impactor asteroid out of the sky before it hits! 

Plunge into this primordial planetoid now: Play the free beta version here today! The beta will be playable right up until the DLC goes on sale. Remember to back up your saves first. 

The Prehistoric Planet Pack will be out on Steam, WeGame, and Epic at the same time. It will cost 7.99USD.

That doesn't seem like a very optimal way to grow Ovagro Nodes

I will either become something beyond a human who can play games without sleep or rest, or I’ll simply die.

Great.  I just finished blowing up the asteroid last night - in 500 turns (i'm very rusty).  

Looking forward to see what can be done with Iridium - is it mostly useless?  is there another way to get more?

You get more Iridium from space-POIs that turn up. But 500 turns for the impactor? I though you get 200 before you get hit?

You can change the coming impactor arrival time in the game config when you start a new game.

Thanks, did not check that. I also just saw that Bionic power consumption can be adjusted. All good then.

Hmmm. Still not available???

It's just lunch time.
according to my observations, if Klei says that it would be released on Thursday, then you should expect a release deep into the night from Thursday to Friday. In my time zone, of course.
so, in about 12 hours.

In my experience, most steam releases happen at 10AM PST. So just under 9h from now.

But sometimes the files don't propagate to every Steam server at the same time, so there can be staggered timing.

Happy new year everyone!!!
