I started researching and found Fil Romero's drawing, on which I decided to base my version of the Combustible Lemon Launcher. So please visit her Deviant Art page to see more of her awesome work:

The materials used for this build were pretty much styrofoam, PVC and paper mache, since I had to work on this in my spare time and on my own money I couldn't spend on more expensive materials and I had to work quick. The gun has some electronics too but the LED light was not noticeable on camera due to the strong lights I used to light up the scene (1200 watts in total!), I had to re-touch the LED light in post-production.
The music was taken from the game's Original Soundtrack.
Programs Used:
-Adobe After Effects CS3.
-Adobe Photoshop CS3.
