Welcome to the future of space warfare! Star Fleet II: Krellan Commander is a retro game that puts you in command of an advanced space battlecruiser and tasks you with exploring sectors, fighting and boarding enemy ships, and invading planets. Manage your ship, crew and escorts effectively and find your way to victory!


Star Fleet II: Krellan Commander is a complex and detailed space war simulation. Starting with just a single Krellan battlecruiser, as you rise in the game's seven ranks (each rank has five missions), you'll gain more complexity, such as escorts, planetary invasions, and eventually full sector command.

Each mission is a randomly-generated galactic war sandbox, and while you have specific objectives, how you accomplish them is entirely up to you. No other space game gives you this much depth, detail and control. Fight, board, and capture ships, send landing parties and full invasion forces down to planets. Bombard cities (sparingly, as you want as many cities intact as possible) from orbit while avoiding planetary defense fire from high technology planets. It's all here.

As Commander of a Krellan Battlecruiser with four destroyer escorts (forming a "battle fleet"), your mission is to explore the star systems of the United Galactic Alliance looking for planets to conquer and Alliance warships to destroy. Your ships are equipped with the latest technology, including phasers, homing torpedoes and deadly obliterator pods. Also at your command are elite shock troops for boarding and capturing enemy vessels, and legions of Krellan warriors for planetary invasions.

Star Fleet II gives you more depth, complexity, and realism than any space war simulation before or since. But that's not all! Star Fleet II is actually two games in one. Every time you invade a planet, Star Fleet II switches to a complete planetary invasion game that allows you to control the conquering Krellan forces in their attempt to overwhelm the planetary defenders.


Version 1.0 of this game was originally released by Trevor Sorensen and Interstel Corporation in 1989. It was initially rushed to market in order to get it in stores in time for the Christmas season. The result was a very buggy release. Debugging and development continued until 1991 with the release of an enhanced and fairly bug-free Version 1.5B, which is the most common version found on websites that provide old games. Then, in 2018, with the developer’s original 486 PC back in action, the author, Trevor Sorensen, resumed development to produce what is now 2.0.

As this game came out in 1989, it has absolutely no multithreading of any kind. Therefore, due to the real-time nature of the game (although you can pause at any time), sometimes responses to your commands might be delayed a moment. Have patience with the game, it's doing a lot at one time, from calculating AI for dozens of ships and even individual torpedoes, to managing your ship's systems and much more.

While the game might look daunting at first, there are eight fully-documented and detailed tutorials in the game to help teach you everything from basic navigation to ship combat to planetary invasions and more.



  • 35 galactic regions with over 1,700 star systems and 1,000 unique planets to explore and conquer

  • Each planet has its own unique surface, which you can view from orbit

  • Over 10 different types of starships, including: Alliance heavy and light cruisers, destroyers, frigates, scouts, freighters and starliners; Krellan battlecruisers, destroyers, troopships and supply ships

  • Ship-to-ship and fleet combat

  • 12 critical ship's systems simulated

  • New commands include; communications, intelligence, strategic command, logistics, obliterator pods, science, medical, planetary invasions and more
