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!

0 comments by Jeoo on Jul 7th, 2015

Greetings, Interplanetarists! Team Jolly Roger here, with another little patch that should greatly increase the joy of demolishing AIs. Also, we'd like to give you a quick update on Interplanetary's state, the pace of future updates and such. Let's get right on it!

AI Speed Up!

As some of you have pointed out, the AI can sometimes take its sweet time calculating attacks. The more AI players and the higher the difficulty, the longer it takes.

To alleviate the frustration, we've made changes that should make turn processing much faster. The AIs now start their calculations already during the player's turn, which in the ideal situation can make turns lightning fast! This is something that people on our forums have suggested, and while we initially had to keep it simple, this is obviously the better way to do things.

My God, it's full of AIs!

On top of that, we have some little tweaks, but nothing massive.

Interplanetary Patch 1.0.6378

  • AI performance optimizations
  • Minor Load Game performance optimizations
  • Fixed typos on Event Log

For previous changelogs, head for the forums.

Situation Report

Overall, Interplanetary 1.0 launch went quite well! We got a nice burst of new players and the added features were well received. Having given it a little time, we determined that the launch was indeed successful enough for us to continue updating the game, but not quite on the scale we originally thought we might. All promised features are still planned, but the timeline had to be expanded. Of course, possible fixes of all sorts take priority over features.

Some new issues were discovered, as is customary when releasing a game, but we did and are doing our best to handle them. The most persistent and serious problems have had to do with the game getting stuck on turn processing. There have been different reasons that have caused this to happen: networking problems, AI issues or just unrelated bugs causing the game get confused.

Not this one, though! Flying buildings were harmless fun.

While we've done our best to try and eliminate as many of these problems as possible, we've wanted to also add two fail-safe features: Reconnect and Online Saving. Both features have been promised multiple times and reconnect was technically ready when we discovered a huge problem. The system, as it's currently made, works, but it is very slow. In common cases, reconnecting to a match can take over 10 minutes, which brings the match to a halt for all players.

Needless to say, this doesn't work. Not only is it possible to accidentally get the game stuck, but this feature would also be very easy to abuse. Since Online Saving is part of this system, we've had to push back both features. Sincere apologies for the inconvenience! The features are still coming, but we've passed our internal deadline for them, so their programmers have to move on to different tasks. We can't say exactly when it will be possible for us to patch in reconnect and online saves, but it will be a while.

Basically, the pace of updates won't be what it was during Interplanetary's Early Access run. Even though many of us need to switch to other tasks, we will still keep a close eye on the forums and use every possible chance to continue work on the planned features. There's still a nice big list of goodies planned!

If you have any questions, concerns or bug reports, the forum is a pretty good place to find us! You can also find us on Facebook and Twitter or just shoot a traditional email to info@teamjollyroger.com. Another nice way to keep updated on the development is to join our mailing list at www.interplanetarygame.com.

Keep on blasting!

It does depend a lot on the "mood" of the AI. Of course, we're still developing it, but an aggressive strategy often is a very effective one in this game.

Hi! At the moment we don't have any plans for demo. But, perhaps, you could leave us your computer specs, so we can let you know if the game would work for you :)

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.
