1. First copy an image from your document (If you didn't have any , google it) to the canvas and zoom in to it. then use brush tools and draw the outlines and when you've done .. delete the gun and use the "free transform" tool to shrunk the gun image. you have it , use the same way to sword...
2. First , download any sound effects from any sound effect websites. then , in your project , click "import" and select "import to stage" . select the sound effect , when it appears to the library (the long window at the right screen) drag it inside your canvas and right to the location where the sound supposed to be.
3. glow (glow an object , used on every simbol) , rebel (most likely an effect that drop inner ligh shadow in your simbol , and make it 2D like. ) , shadow (the usuall shadow effect , select "knock out" for inviciblity effect .. kinda ... shadow can change colour too.) Try the other effect too , use filter on a simbol and start experimenting.
