This story is based in the Fallout world, so a good 85% of the creatures and weapons are somewhere in the Fallout Wiki. Googling "Fallout (Creature/Weapon name)" should yield the correct pictures, and descriptions
A few examples are the Mole (Rat), Giant Ant, and the Laser Pistol

However, some things I made up, but are in the fallout style. An example is the Chinese Carbine that Barrett uses. It's based off the Chinese Assault Rifle, but I made the Carbine version in a program called Pimp My Gun.

I'm very interested. Pm me.
