Post news Report RSS Interplanetary Arrives to Steam Early Access This Friday!

Surprise! We're finally ready to bring Interplanetary to Steam, starting the next step on its grand journey!

Posted by on

Surprise! It's finally time to move to the next level: the Steam Early Access version of Interplanetary will be released April 18th, which is this Friday!

We decided that going Early Access was a natural continuation of Interplanetary's journey, as we've already had close collaboration with its players during development. By continuing on to Steam, we'll be able to reach a much wider audience than ever before, which helps the development a huge amount.

Like usual, buying the Early Access version at a reduced price will also give you all the future updates until the game is finished and you'll be able to better influence the direction of the game through your feedback.

New Features

For the Early Access release, we've prepared an exciting new feature: Superweapons. These are unlockable through the Tech Tree and will wreak serious havoc with your enemy's planet.

This planet's going to have a bad time.

Currently, we've implemented two superweapons:

  • Asteroid Diversion
    • Diverts a group of asteroids towards the enemy planet, causing massive damage. Works similarly to the railgun, except that the starting point is the asteroid field at the edge of the planetary system and you'll be shooting a cluster of space boulders instead of one small shot.
  • Solar Laser
    • An accurate and powerful weapon, the Solar Laser is fired from it's own orbit close to the sun. Unlike with normal lasers, it can shoot to any direction, unless there are other celestial objects blocking its line of sight.

These weapons are pretty devastating, so make sure you get them before your opponent does!

In addition to superweapons, we've been doing a lot of smaller updates all across the board. Some of the major ones include the ability to have hotseat matches with up to 4 players and many graphical and UI-fixes. There are also plenty of balance adjustments, so make sure to weigh in with your opinions.

Time to get hyped!

That's good to hear, but I actually meant distribution channels, sorry. :) Will it be released outside of Steam?

Oh, right. It's just Steam, for now, but we'll get to those others later too.
