So in the E3 interview Brad did (http://www.giantbomb.com/e3-2012-dead-space-3-interview/17-6213/). Brad asked if you could turn the plasma cutter sideways, to which the response was "If that's what you want, you can do it".

Also just previously mentioned was the fact that Isaac made his own weapons, and the fact that they were taking that to the next level.

So my guess is that there will be some sort of crafting/customization that lets you make the weapons interesting and unique.

It might be as simple as slapping together two different primary and secondary modes. Thoughts?
