Welcome and thanks for looking into this thread!
Last month I started a new mini Unity 3d project for learning.
Click below to play!
PLAY
The player is a flying stone bird thing with wood (don’t really remember why).
The player can fly around but it cannot attack or defend itself, that’s why you have another
thing flying around you. The player can give a limited amount of orders to shoot, stab or make a shield.
When attacks hit the shield it results in an increase in lost hit points.
Controls for direction:
ASWD, Space and Left Shift.
Controls for actions:
Left Mouse is charge, Right Mouse is shield and Middle Mouse is shoot.
At first it’ll probably be very confusing, don’t worry that’s the point.
The player isn’t suppose to have complete control over the attacks, but the longer
you play, the better you’ll get at planning attacks.
Now that that demo’s done, I’m working on a proper space robot shooter.
And there the player does have a gun, shield, sword and lots of rockets + jet-mode 
Screenshot of an early version of the model can be found on my site:
