Lately, I noticed fewer and fewer people have logged on. I decided to try and help out, by giving some suggestions.
First, I think some new opponents are in order. How about a few boss zombies? There could be one every 10 levels from 20-70.

Squad Competitions:
And maybe add some squad competitions, like in HU. Every half our, there's a 3 minute registration for it. All squads that registered are teleported to a special map.
You could cancel the special abilities, like dropping medic boxes and barracades and such, and spread some out through the special map. And the winning squad could be the one who finds the right flag. Or if no one finds it, the squad with the most kills. The winning squad could get a special prize, maybe each member gets a gun.

Veichles:
And speaking of guns, you could add some more, maybe a flamethrower. I also think that car's are REALLY too expensive. 150 thousand isn't easy to get. I say put it down to 75 thousand. And add a tank, it could be slower than a car, but it could run over and have it's own special ammo system. Maybe 5 auto, then it reloads one every 30 seconds.

Tutorial:
A tutorial could be good, for some of the beginners. Scroter was the guy who really helped me out. The game seems confusing at first, so a tutorial wouldn't hurt.

Training zone:
Then there could be a training zone. Not really experience training, but when to shoot, when to throw the 2nd item. Like the grenade.

Unlockables
And maybe unlockables, maybe some cool unlockable videos. And medals, one for reaching a 10,000 career mark, 25,000, 50,0000.

Recorder item
An item that records a fight, that you could put in one of the TV's to watch. Like, right-click on the TV and click, watch recording. So you could just watch epicness without worrying about dying or anything.

And maybe, just maybe, a new look to the game. Polish everything up, try to make it shinier.
I hope you now see all the things that could make this game better, and I hope you listen to this suggestion. I know this looks like a lot of stuff at first, but Falacy made this game! The Falacy, who made DBZHU with over 100 people playing. It's like the biggest game in Byond. The person who could make DBZHU, can certainly make a better Paradise City.

P.S. Please actually put these ideas into consideration! Tons of the other posts suggesting updates have been totally ignored, so stop ignoring! Paradise City is dying, poeple are quitting, so step up and make the game more permanent! I bet you could make this game as good as HU, if you actually went back to working on this. These are not fantasy ideas. These are real ideas!!!
