Endless Sky is a 2D space trading and combat game inspired by the classic Escape Velocity series. Work your way up from a relatively wimpy shuttle, cargo ship, or fighter, to a highly upgraded and customized flagship or to a massive fleet of warships or freighters. Earn money by carrying passengers or cargo, escorting convoys, bounty hunting, or plundering and capturing enemy ships. Take sides in a civil war, or ignore the story line and just enjoy exploring the galaxy and blasting pirates.

The main story line takes about 8-16 hours to play through. The galaxy contains hundreds of star systems and planets, and several alien species with their own unique technologies. You can choose between more than fifty ships and several hundred ship upgrades. A plugin system allows anyone with a text editor and a paint program to create new ships, weapons, or missions, and the galaxy editor can be used to add new star systems and planets.

Endless Sky is free, open source, and cross platform (Windows, Mac, and Linux). Over time, the game universe will expand as contributors add new missions, story lines, alien species, places to explore, sound effects, and artwork.

For more information, please visit the website or read the player's manual.

Over the past few days I have been working on the Republic Rising mod for Endless Sky. I would like to share the new content, features and add-ons with you.

Republic and Separatist forces have been implemented alongside a new galactic map:

Full list of Republic Rising UnitsGalactic Map

The galactic map will be expanded in future and a campaign for both factions will be added. The unit list is not permanent; I will add more ships in the future including flagships such as The Resolute and The Invisible Hand.

The galactic map now contains Contested Areas or 'Flashpoints'.


Flashpoints are continuous space battles. This huge battlefield can be salvaged for damaged fighters or cruisers when the two sides temporarily pull back to re-group. Participating in one of these fights requires a very big gun and an even bigger ship. The best strategy for engaging enemy forces in a flashpoint is to run in screaming 'IMMA FIRIN' MA LAZERZ!' and spin in circles till the enemy perishes in a ball of molten plasma.

While designing this mod I felt capital ships and carriers needed bigger fighters bays. Much bigger fighter bays. So big that I almost reached 'Enuff Dakka'.

A typical carrier can hold 10-15 fighters whereas capital ships can hold 20-30. This is a big shift in the standard gameplay terms, but I really wanted to see a huge space battles.

Republic Rising will contain multiple add-ons in the future. The most recent add-on is the Interceptor plug-in:

This simple add-on includes all the Fighter class units but converted into Interceptors.The add-ons could contain anything from new technology or additional ships that people may or may not want according to what they want their game to be like.

This is all the information I have leading up to the 1.0 release, but more content will arrive soon. Thank you for reading and may the force be with you!
