If you could add one weapon/feature to your ship...

Subwoofers on the outside, connected to my radio.

I'd blast various types of music depending on the situation:

• About to mass-murder some monsters: Jaws
• When it's Friday: Friday
• Long trips/tedious tasks: Whatever Touhou music I'm listening around that time.
• Flying through space: Nyan cat (May ever tie a rainbow banner to the tail fin)
• Want to annoy jerk on Multiplayer server: Rick-roll/Tololol/Running in the 90s/Another song that gets annoying over a long period of time.
• Want to mess with friends on multiplayer server: Dial tone

 

Feature? A space swimming pool.

Weapon? Snowball launcher!

 

Drone Hanger, which builds drones which hyperbeam things.

 

But if it never existed, then you wouldn't have shot it, and you'll end up never firing the cannon because everything that you would shoot doesn't exist! And then the owners of the previous ship would send another ship in it's place! That would cause a time loop up to the point when the planet the enemy ship came from doesn't have enough minerals to create a ship to send to you, devastating large space empires, and maybe even preventing your acquisition of FTL technology, which in turn causes a paradox!

OT: Easy-bake oven.
I WANT MY MINIMUFFINS.

 

I was just thinking of adding some external speakers, only I'd be blasting stuff like Synchrogazer or Meteor Light.

Voice over radio: "TIME PARADOX!"

 

surround sound lmao xD

 

GatLaser turrets that can be controlled manually, or set to auto-attack.

and cake.

every ship must have cake.

 

Coffee maker. It essential to my (and everyone around me) well being.

 

Man! I should have added this!

 

Drone hangar! Every 5 seconds they are spawned, and attack any enemies at range! I would never have to bother with enemy ships again!

 

Nova cannon. It uses magnetic fields to fire gigantic shells at near light-speed.
If that fails, I'll have that big laser from the Death Star.

But I wanted ARGON!

 

id put on it the cannon ganondorf used in SSB brawl. the animation on the gun was so cool and powerful

 

Ooh! The secret weapon from spore:

Staff of Life! It fully terraforms a planet in one hit, and comes with 42 charges!

 

A huge Gauss Rifle!

 

something that launches this and makes this

 

The ability to transform into a super mega giga robot!!!!!!!! But I'm sure that'd be impossible to code in

 

Stellar Converter
Prepare your brain for Razzle Dazzle!

 

A microwave. Those things are so damn useful.

 

That thing Darkseid had that let him have anytime
Then I'll have all the unreleased copies of Starbound I want!
