There is a problem with interplanetary civilizations: developing them takes more resources than a single planet can offer, and sometimes even a planetary system is not enough. Especially if you have competition.

In distant cosmos, two sister planets have reached a rather tense situation. The ancient greed, inherent to both civilizations, has driven them to most dramatic measures: the building of massive cannons, aimed directly at each other. Let the game of interplanetary artilleries begin!
Interplanetary is a turn-based strategy game for PC, Mac and Linux, featuring both single- and multiplayer modes. It is inspired by classics like DEFCON, Civilization series and old-school artillery games.

Your goal is to cause damage to the enemy's planet and to protect your own. Manage your planet's infrastructure using the limited natural resources and research new technologies to develop even mightier weapons and defenses.

At the end of each turn, there is a chance to shoot your interplanetary guns and try to hit major strategic points on the enemy's planet. Be precise, and you might manage to navigate your railgun slug around other planets and their gravity wells, straight into enemy cities!

Available now on Steam Early Access.

Featuring a cameo appearance by everyone's favorite blue sun.

Once again, it's time to send a new update out into the big world. Good luck out there, try not to break down immediately! Like that ever happens, heh...


This time we've updated in a couple of small features that serve as a base for something a bit bigger that's coming in the future.

First we have a new window for interacting with buildings. When clicking on a building, you'll now be greeted with a lot more info than previously. The functionality remains the same currently, but you can now easily see the numerical values of building health, visibility and production, for example. Makes it a bit easier to utilize advanced strategies.

If that's not enough data for you, we're now introducing the Interplanetary Codex. It's an ever-growing in-game database of all things Interplanetary. You'll be able to use it to dig deep into building stats, for example, or just read about the real life functionality of railguns. More entries will be coming with time, so stay on the lookout!

Since we're opening the hood a little bit and letting you in on the number crunching, feel free to comment on any values that you feel should be different. We obviously appreciate outside opinions; why be in Early Access otherwise?

Aah, more reasons to showcase the awesome 2D art.

These are the main features introduced in the update, but there are still plenty of smaller things and tweaks in there. Check out the changelog for more!

You remember Whack-a-Dev, right? That's the event where members of Team Jolly Roger host games of Interplanetary and duke it out against the players. This Saturday we're changing it up a little bit with a surprise guest: the Interplanetary AI! We're letting the players to have a little sneak peek, by letting the AI do the battling for us, under our supervision.

Do note that the AI is still early in development and this is its first time in real action. The final implementation of the feature is still far away. Check out the Steam Announcement for more info!

Interplanetary is available on Steam Early Access

I posted a comment here and got a alpha key in a PM over a year ago, thing is i never knew PM's where a thing on desura XD. Only found out about the message today... oops. anyway before i found out about the message i was bored and looking through my bookmark tabs and found a link to this page buried away in there. after taking another look i'm impressed. nice to see it still being worked on and even green-lighted too. I've seen lots of cool larger scale games like this and usually after the first little while of development the game just kinda fades away but its great to see this alive and well.

How will we colonize other planets if there are no spaceships? Teleportation? *Confused*

The exploration of space is not completely absent from IP universe, it's just nowhere near as advanced as in most scifi universes. As in, no starfleets. We imagine the entry level to be what our technology might be in 50 years or so.

I was really happy when I saw this get greenlit, well done! One question though: will it be available through other, non-steam means as well?
