Save file

Save files for the game are stored in %LOCALAPPDATA%\Introversion\LastStarship\saves on Windows, ~/Library/Application\ Support/LastStarship/saves on Mac, and ~/.local/share/Steam/steamapps/compatdata/1857080/pfx/drive_c/users/steamuser/AppData/Local/Introversion/LastStarship/saves on Linux (using Proton). They are stored in a plaintext format and end in a .space extension.

Common modifications

Enable mutli-system simulation

Multi-system simulation, introduced unofficially in Alpha 7, allows you to have ships in different systems at the same time. It was officially added to Industry mode in Alpha 8, but can be enabled in Free Roam and Survival modes by adding the line MultiSystemSimulation true to the top of the save file (before the HUD section).

Add items to the Trade screen

If you are stuck in a system with no Trade screen or the Trade screen is missing an item you need:

1. Save and close the game.
2. In the directory listed above, find the .space file corresponding to the saved game and open it in a text editor.
3. Search for a line containing TradePossible. Set that to true.

   Note: There may be multiple Trade sections in the system archive save file. Make sure to use the base section that is not indented.

4. In the TheirStock section below, update or add the desired line using the item code from the table below. Spacing is important, so make sure to match it. The number can be adjusted to the preferred amount.
5. Save the changes, run the game, and load the save.

Add items to a shuttle

Some items, like hull breaches, are technically just like any other items, but they cannot be purchased from the Trade screen, even with the trick above. In this case, it's necessary to modify a shuttle's inventory as it delivers cargo.

1. Purchase something or initiate a mission delivery.
2. As soon as the shuttle appears, save and close the game.
3. In the directory listed above, find the .space file corresponding to the saved game and open it in a text editor.
4. Find the section for your ship. It should be the first section beginning with BEGIN Layer. Find the line BEGIN Deliveries inside that section.
5. In the the Trade section below, update or add the desired line using the item code from the table below. Spacing is important, so make sure to match it. The number can be adjusted to the preferred amount.

Refill a fuel tank

If your ship runs out of fuel, but you have a fuel tank installed:

1. Save and close the game.
2. In the directory listed above, find the .space file corresponding to the saved game and open it in a text editor.
3. Search for a line containing Resource Fuel. Spacing is important.
4. Ensure that the line belongs to a tank and that the tank belongs to the correct ship. Player-owned ships are listed as FriendlyShip type.
5. Update or add the corresponding Quantity line to add fuel to the tank.
6. Save the changes, run the game, and load the save.

How to setup an AI fight for two player-created ships

Game Version: Alpha13B - Steam

Note: You'll need your favourite text editor. I use https://notepad-plus-plus.org

Note: For readabilty in this guide, example save-game text is indented (by 1 tab), but it isn't in original save-game files.

TLS = The Last Starship

AI Strategy

You can assign an "AI-strategy" to either ship, which determine how they fight:

StrategyVeryCloseOrbit:  Broadside orbits within Gatling gun range.

CloseRangeAggressive:    Broadside orbits in cannon range just outside of gatling gun range.

MediumRangeOrbit:        Broadside orbits within far end of cannon range.

LongRangeSniper:         Broadside orbits at railgun range well outside of cannon range.

FastMovingJet:           Forward facing strafing Runs, fly's straight at opponent then circles around to do it again.

Instructions

• In TLS, create your own ship and export it, or subscribe to a ship on steam workshop. Or alternatively, download a ship from a trusted website.

TLS stores ships in the ship-folder: "C:\Users\<your-windows-username>\AppData\Local\Introversion\LastStarship\ships"

• Each ship has a ship-file named "<ship-name>.ship", and an image file named "<ship-name>.png".
• Launch TLS, and select Creative Mode -> Create New Ship
• Go back to the main menu (by pressing the escape key) and select "Import Hostile", then select a ship to import. Note the name of the imported ship, which will appear in red at the top right of the screen. We'll refer to this as "ship-1".
• Repeat this process to import a second ship, "ship-2".
• Go back to menu and select: Save Game -> Create New Save, then give it a helpful name (e.g. ship-1 vs ship-2).
• Go back to menu and select: "Abandon Game".
• Open the save-game folder (not the ship-folder):

"C:\Users\<your-windows-username>\AppData\Local\Introversion\LastStarship\saves"

• Open the save-game file (.space file) you just created, using your text editor.
• Text search for "NEWSHIP", it should look like this... then delete this whole section including the BEGIN and END.

BEGIN Layer      
	Name                 NEWSHIP  
	Class                Ship

	END

	BEGIN Deliveries 
		BEGIN Trade      END
	END
END

Info: occasionally there are other random ships named "NEWSHIP" with a much bigger definition. You can just ignore or delete them.

• Text search for the ship name you noted for "ship-1", you should find a section that starts like this:

BEGIN Layer      
	Name                 "CANNON WALL FUN MK3"  
	Author               ZENRATH  
	Class                Ship  
	Id                   1612  
	SystemId             1  
	Type                 HostileShip  
	Offset.x             0
	Offset.y             0

• Change the Type from "HostileShip" to "FriendlyShip"
• Optionally, set both Offset.x  and Offset.y to "0".
• Text search *from your current position* for "Strategy", then change the word immediately following "Strategy" to an AI-Strategy for ship-1.

BEGIN ShipAI     Layer 1612  TargetId 1610  LastLaunch 153.87734406203825  Broadside -1  Engaged true  Strategy FastMovingJet  END

•  Text search for the name you noted for "ship-2", you should find a section that starts like this:

BEGIN Layer      
	Name                 DEFIANT  
	Author               RANAMAR  
	Class                Ship  
	Id                   2508  
	SystemId             1  
	Type                 HostileShip  
	Offset.x             1500
	Offset.y             1500

• Leave the Type as "HostileShip"
• Optionally, set both Offset.x  and Offset.y to "1500".
• Text search again *from your current position* for "Strategy", then change the word immediately following "Strategy" to an AI-Strategy for ship-2.

BEGIN ShipAI     Layer 2508  Broadside -1  Engaged true  Strategy CloseRangeAggressive  END

• Save the changes to your savegame (.space) file.
• Return to TLS. Select "Load Game", and the save-game you just edited.
• Quickly pause the game.
• At the top right of the screen, select ship-1, whose name should now be in green.
• Activate "Battle Stations".
• Un-pause the game, and enjoy the show!
