I love the MP7. I didn't love the SpecOps. I love both now.
Changed Stats:
Concealment = 25, Boosted up from 23 to be realistic, as the MP5 has 24 and the MP9 has 26
Ammo Pickup = 5-9, I just rounded up from 4.8-8.8 for simplicity
Now shoots through walls, body armor, shields, and enemies!
The point of the real MP7 was to be a highly compact armor-piercing PDW. It's a gun good at penetrating in real life, so I thought that should be the case for this game. It now has its own niche, as it was previously just a significantly worse AK Gen-21, having less ammo per mag, less total, higher damage falloff, worse pickup, and worse modding. It does NOT benifit from sniper graze, and it still can struggle with ammo on higher difficulties, but it now has a purpose. The gun works in multiplayer flawlessly.
The attachments have yet to be adjusted, but I plan on buffing the extended magazine. The vanilla one is not great.
