A few suggestions

[XaeroSignal]

Let me start by saying this game rules. Here are my suggestions for ways to improve it:

-Different voices for different character models.
-Female character models.
-.45 Caliber options for the lighter weapons. aka USP/MK23 pistol and UMP.45 SMG for medics.
-Flashlight attachment upgrade purchasable for other weapons.
-Night vision goggle upgrade.
-Sprint button.

I'm sure some of this stuff has been suggested before but honestly it would take me more time to search the forums and look at all the threads the search brings up to see if these things are mentioned than it would for anyone to read through it and see that there are duplicates. Sorry
