The smaller guns like the P90,MP5,Uzi? Scorpion? are completely useless.It takes almost 1 full clip PER Zombie.Accually ALL of the guns need a damage increase except for the DE.If you nerf the best gun in the game you better Bump up the damage on All of the other guns Significantly Or make the zombies have 1/2 the health.
The zombies do seem to have WAY to much HP VS the other 6 or 7 ROTU servers I've played on.This is supposed to be a Fun zombie killing game that Anyone can have fun with so throw Realism out the window and make the guns overpowered,they're supposed to be that way.
The original creator of ROTU developed it up to v1.8 or 1.9? (I forget which) then someone else took it over and tried to finish it but actually fucked up a few things such as the ray gun not working and most of the other guns were made pretty much Useless because of the low damage and Map compatibility suffered Greatly.Most of the Original ROTU maps and Alot of later added ROTU maps made by the original author no longer work.This mod hasn't been worked on or patched sense Jan 2014
They did however upload the entire Source code for everything in 2.2.2. 2.86GB of stuff to monkey around with here @@Sammy
