Don't let this discourage you however, the Shotgun is a very formidable weapon and ammo really IS abundant. The Shotgun has plenty of ammo through the game, especially when you don't use it early on like me. Weak Shots that do about the same dmg all around. Useful for killing: Anything in your way. It is the first ranged weapon available to you, ammo is fairly plentiful, and because the Assault Rifle is available at level 6 standard skill, this weapon only gets better with time. This WILL BE your best weapon until you gain enough skill to use the Assault Rifle. I'll post a list of weapons and information about them so you can form your own opinions about them.

For example, although you can find some exotic type weapons early on, the ammo for them doesn't become available until much later on, and by that time, most your Upgrades have been distributed elsewhere. Contrary to common sense, most 'strong' weapons really don't have much of a purpose for various reasons. Without them, you wouldn't be able defend justice! The weapons of System Shock 2 are not very well balanced.
