I'm hoping this game will have unique versions of all the weapons (Like Fallout 3 did) that will have distinct advantages and disadvantages.
To start it off....
An assault rifle that shoots explosive rounds that will decimate an enemy's armor, making them more vulnerable with every shot. However, the assault rifle will either use more ammunition per shot or have a special ammunition of it's own.
What all do you want?
Yeah, there will be loads of cool unique weapons I've heard, but this time they actually look different too!
An assault rifle that shoots explosive rounds... I'd rather have different ammo have different types instead like Full Metal Jacket, Armor Piercing, Hollow Point (Incendiary, Explosive if you want, but I'm not too keen on them) and they'd be effective and ineffective against certain enemies and armor.
