Althought your project is focused on team PVP, i hope you can solve most 2238 problems:
Empty locations = no players, no fun.
Absence of any funny gamemode (capture the flag, ...)
50 weapons in game, only 4-5 are usable in PvP :/
Sandbags, mines, traps...simply items that could bring more variables into static city streets.
And please, dont make the same mistake like on FODE. Maybe you did not realize that in your pubescent vulgar shooting, but almost every FODE city location is s...t. Why? Because it is sooooo HUUUUUUUUUGEEEEE, and you will never ever fill it with players, even you will have 500 hundreds online per day (trust me, you will have not).
