Centuries have passed since the time when "The Unknown Resistance" tried to send four giant asteroids at our home planet. At the space shuttle academy, us cadets are frequently told of the great deeds of the legendary hero pilot and how he crushed the resistance with nothing but a single shuttle. But lately a rumor has made its way around among the cadets. "The Unknown Resistance" have once again started to move and are stirring up trouble ever closer to our home planet.

As a last year cadet I will soon soar across the sky, just like the legendary hero pilot. Even though I am enthusiastic for my graduation, the current galactic situation is no doubt a cause for concern. Will the graduating cadets of my year be enough to fill the void in our navy? Will our home planet be able to repay our debt to higher powers? Will I too be able to defeat "The Unknown Resistance" if the time would come?

SEG Space shuttle II is the long awaited sequel to the intense retro experience of SEG Space shuttle.


Intense missions:
An exciting campaign with over 20 missions, multiple additional side missions and even an seemingly infinitely long trial mode to test your skills. In total the missions add up to possibly hundreds of hours of gameplay.

Multiple interesting factions:
"The Unknown Resistance" makes its return as well as the classic SEG faction itself, but this time around even more factions join the fun. Everything from the xenophobic Marsh militia and technologically advanced Imperial navy to the mysterious Lunar Wraiths and even some standalone actors.

500+ Items for ship modification:
The classic ways of modifying your ship during missions through batteries and weapons return as well as the addition of many new item types. Balance the power usage from the batteries to the reactor output and figure out the optimal balance between ship agility and firepower.

20+ Unique playable ships:
A wide array of uniquely feeling ships with their own looks and playstyles. Each ship has its own modifiers giving it a slight unique edge over the other ships in its own respective area. What ship will suit you the best? Will it be the high DPS Marauder ship or maybe the trade oriented Merchant ship?

100+ Challenging achievements:
A huge variety of engaging and challenging achievements await the devoted. Most achievements additionally unlock various exciting and helpful items to aid you during the missions.

Online co-op:
Conquer the asteroid fields together in this brand new online cooperative mode. All missions and modes are available to be played together with your friends in the online co-op mode, even if they do not own the full game.
