For those of you who are more tech savvy you can pretty much skip the guide by just knowing this:

• You combine two ships in MS paint
  
• Save as a new png
  
• You are done!
  
• Simple yes but I would like to make a guide on exactly how to do it and give some pointers as well.

• Ships work based upon colors representing different material (as in their literal value in color) the color guide can be found online or in your game files probably.
  
• The white background color of MS paint will not spawn any material so it is good to go.
  
• Ships may get cut off in the process, or may be corrupted originally.

The following will be a step by step guide with lots of images, and I will give some pointers. If your ships are spawning and falling apart it is likely the actual ships fault and not the editing process.

Step 1: Locate your games ship folder and create a new folder. Call it multships.


Step 2: Now that you have made your folder open up paint or your equivalent software on your pc and stretch out the blank space. More space is better as that will allow you you fit more ships.

Step 3: Click the import button and go to your ship folder to pick the ships you want in.
Step 4: Format your ships so that they are the length away from each other you want, and cut out the extra white you don't need. It should look something like this:
Step 5: Save this new image to your multships folder.
Step 6: Congrats! You now got two ships to sink.
