So, as a photographer who knows a thing or two about optics: does a small aperture lead to longer range?
Haha, I see what you mean, but not in this aspect
The aperture is the output control from the core of Eo, bigger the aperture - more energy is released per shot.
THE BARREL is the thing that determines distance, noise, accuracy - you can make it act like an Uzi with a small barrel or a sniper
For example, lower the aperture diameter, and shorten the barrel, and you can shoot hundreds of wild bullets without overheating or using too much power!
Amp up the inputs, and crank up the Shell transformer, along with opening the aperture all the way and fully extending the barrel - shoots a MASSIVE CASCADING ENERGY BLAST-OF-AN-EXPLOSION!! But, Eo would need a long time to recover ~ leaving you defenceless!
And that's just a couple of examples
There will also be upgrades!
