Enhanced weapons realism and diversity. Counting a total of almost 200 unique weapon profiles.
Here's another pic of the New Ordnance guns in MISERY 2.0. They're more spread out here so you should be able to see more of the variants.
On a side note I got some news, all the guns in New Ordnance will have brand new animations! (However not in time for the MISERY 2.0 release) That's all I'll say for now ;)
