Pros:

Overall nice model
Nice choice of infected to replace

Cons:

Consistency breaking currently
No FPS arms.

Conclusion:

Mod definitely has potential, I'd rate it 3.5/4 in it's current state. If you are able to update the mod in later versions, that make it so it doesn't "break" the consistency, it'll definitely become a 5. FPS arms would be a nice touch, but aren't "required" to get 5 stars.
