Free spaceship software for linux

Blackshift, a satisfyingly difficult puzzle/skill/action game. You should try it out. I think youd like it. Basically, its a top down view of a subterranean maze, where you have to blow up a frozen alien in order to continue. There are about a hundred levels to beat, each one more evil and twisted than the last.
Main features:
- Missiles
- bombs
- grills
- spaceships
- robots
- buttons
- keys
- doors
- teleports
- angry red faces
- diamonds
- eyeballs
- mirrors
- photocopiers
- pits
- landmines
- aliens
- guns
- blocks
- splitters
- remote controls
- nuclear weapons
RUNNING IT:
If Blackshift wont run when you click the icon you should run it from a console. It worked for me. Explanations as to why are welcome, especially if they arent Because KDE is weird. As always, YMMV.
CONTROLS:
Arrows: Move
Enter: Pickup/Drop
Space: Pickup/Fire
R: Restart
Ctrl+N: Nuke

xplanets shows a simulation of a spacecraft flying through the solar system. With the controls next to the simulation screen you can control the simulation and steer the spacecrafts flight.
The following planets are visible:
- the Sun (yellow)
- mercury (gray38)
- venus (burlywood2)
- earth (blue2)
- mars (LightSalmon3)
Note that the sizes of the sun and planets are not to scale, though their distances are. Showing the planets to scale would mean that they wouldnt be visible. The solar system is rather big, after all.
The planet nearest to the spaceship is indicated with a red circle around it. Its relative speed and distance are shown in the data display.
The xplanets program uses the GTK+ toolkit. It has been built with version 2.2.1, so it should work with any version >2.0.0. It does not work with GTK+ 1.x anymore.

Marauder-ah project is a 2d space fighting game.
Marauder-ah is a set of improvements over "marauder", originally written by Shawn Hargreaves in 1994.
You control a spaceship with a basic weapon, and your purpose is to kill as many people as you can.
Earning money (using piracy or trade) enables you to upgrade your ship and buy deadly weapons.
Game Rules:
Many years from now, in a distant corner of the galaxy, blah blah.
Ok. The rules are simple. Earn as much money as you can, and dont get shot.
When you start the game, you will see a little spaceship in the middle of the screen. That is you. Use the left and right arrow keys to turn, and the up arrow to fire your thrusters. Once you start moving it is not easy to stop. You will eventually coast to a halt, but if you are in a hurry you will have to turn round and fire your thrusters in the opposite direction.
If you fly around a bit, you will probably come across a planet or another hip (HINT: you can see all the planets and ships on the radar display at the top right of the screen).
There are two things to remember about planets. One is that if you fly into
them you get hurt. The other is that if you fly up close to one and then
press ENTER, you go to the shipyard.

StarTrade is a Spacesimulation like Wing Commander:Privateer or X-Beyond the Frontier with 2D world view. You can trade, pirate or work for the Allianze to hunt pirats.
As some of you may have noticed, there was a game-submission a few months ago - "StarTrade", a freeware-currently-in-development-spacesim ressembling Wing Commander: privateer, Freelancer or X. But as most comments were positive, motivating to download StarTrade and give it a go, a problem showed up: StarTrade has been german-only.
I suddendly realized that, when releasing StarTrade for Linux-users, there will be also a large number of potentional gamers who do not speak german, so I started a communityproject in our official forum aiming at a first, rough (well.. we got a slight lack of translators who speak english as their first language) english translation - and here it is. Just visit the official StarTrade homepage (http://www.fetzenet.de), download, after already having installed StarTrade, the English-Mod and follow the instructions.
However, this is only a first attempt - Ive created an international Area in the official forum and everyones welcome to visit us. If you encounter any translation-errors or just want to improve something feel free to join the communityproject - the released version is only a first try.
Thats it. Have fun to everyone who will try out StarTrade e.g. the international Version of it!

CodeInvaders Challenge project is a Java-based, real-time programming game based on the Eclipse platform.

CodeInvaders Challenge is a Java™-based, real-time programming game based on the Eclipse platform. It uses the Eclipse platform and a simple API that allows users unfamiliar with Java to easily compete while they learn the language.

CodeInvaders Challenge gives users the opportunity to pit their Java programming skills against other players in a battle of space conquest. Each player writes a Java class that represents and controls a spaceship. Each ship (class) is placed in a simulated battle along with ships from other players.

The game puts up to six spaceships together in a match and places each of them in a random location with the same amount of energy. The spaceship class allows each player to control his ships thrusters and weapons. The ship can move around to collect energy, attack opponents, and bring energy back to its home planet. Points are awarded for different actions, and the player with the most points wins.

When used in a tournament, CodeInvaders Challenge allows direct, real-time competition between teams. Each player can submit his intermediate solutions and test against the submitted ships from other players. This competition allows each player to learn from the strategies of other players and modify his ship appropriately. After the final submission from each player, the final winner can be found by running a tournament consisting of several rounds and eliminations.
