Futuristic Weaponry

Does someone here knows how to draw futuristic weapons? (laser swords, guns and etc.) I need it for my story

You know how to draw basic wepons? Wepons that exist.

I know how to draw swords and other blade & blunt weapons but I don't know how to draw guns

I have a similar issue with my story. A space sci-fi setting has huge demand on laser guns and stuff... I'm usually basing my designs on what I think looked cool in weapons I've already seen in games and movies (while "basing" is a keyword - ripoffs are baaad).

Well, a good start point is "upgrad" a common weapon into a futuristic one. For example you can plug a battery into an Ak-47 to feed a laser device attached on it.

Laser is pretty simple, a tube conected into an reactor of chain energy. Most of the laser are enhanced wiht crystals (Remember: you have to believe on your guns, don't pretend, believe).

And there is nothing wrong in look for a reference.

But still I need to learn how to draw guns...and I don't know how

Drawing guns...well, frankly said, start with a reference! Remember, that gun can be broken down into shapes; cylinders, squares, rectangles...Take the time to break down the shapes and go from there.

Thanks for the tip

In what your story is based? Depending on the enviroment it may become easier to have ideas;

My story is a game...I'm making a game and I want to draw different weapons for use
