Here is the Standard Pistol (Called the "Guardian" in the game [link]
and the Burst Rifle (Called the "Daybreaker" in the game [link]
. Both are for Insomniac's new game FUSE. The pistol was modified a little before it went into the game (for the better). The turn around on the "Daybreaker" was rather quick so you can still seem some of the photo-bashing that went into it. Not clear in this side drawing, but the "Silencer/barrel extension" is shaped like a grip to match the two handed grip of the character rigs.
I'd also like to point out that this is for a video game and though I do appreciate "real world" functionality feedback, the ONLY thing we're concerned about is how a weapon looks like in the game, and that it matches the gameplay functionality. I cannot stress this enough, it wasn't my project, it wasn't my design requirements. Also these are over 2 years old now.
