Hi everyone!

▶ Watch on YouTube

Here is a summary of the main features of both (full change log at the end of this news):

$5 Worlds of Fire and Water DLC:

Free Update 1.1:

If you see any bugs or issues, don't hesitate to report them on the discord or on the Steam forum. We are only two developers working on the game, so we've probably missed some issues, but we'll fix them as quickly as possible! Edit: if you have some issue, please check if you don't have some old mods still active, as some can break the game. All texts have been translated, but if you see any mistakes, don't hesitate to give us a feedback or directly suggest a fix on Crowdin

Warning: you can continue playing your old saved games, but we strongly recommend starting a new world, as major changes will break a lot of things and require some heavy repairs. However, you can continue playing the 1.0 version by activating the branch v1.0.6 in the steam properties of the game.

The Fire World is extremely hot, so you'll have to cool it down by neutralizing its greenhouse gases and launching shade satellites into orbit! But there are also constant lava eruptions, both deadly and beneficial, as the lava creates mineral-rich basalt patches when it cools down... The lava is completely simulated, so it's up to you to use the terraforming tools to try to control it and protect yourself!

There is also no water in sight, except for a few geysers. But you'll now be able to launch rockets to bring ice comets to your world...

The Water World is a planet almost entirely covered by water. Your main challenge is that you only have a few tiny islands on which to develop your civilization. But by cooling down the planet in a controlled manner, the ice caps will grow larger, causing the water level to decrease and giving you more dry land. You can also use dams and the terrain tool to create even more dry land.

On this planet, the water is polluted by minerals, but you'll be able to filter it to both recover the minerals and allow sea plants to grow. These plants will help plankton spread, which in turn will help produce more oxygen and terraform your planet!

In addition to these two new worlds, the free update brings a lot of changes:
