The Arsenal mod for Kingpin is a conversion of a mod from the game Soldier of Fortune. It was made by Team Atrophy.
Arsenal is similar to the Hitmen mod in that weapons and ammo are given out by the server. Everyone starts with a HMG and works their way down to pistol.
The weapons start with the HMG and every time you kill someone you get the next lowest weapon. Once you've killed someone with the pistol you get the bonus frags and the game resets. The game ends when the frag limit has been reached or the time limit.
Installing and running.
This is a server side mod so you only need these files if you are planning on running a server. You don't need them to just connect to a server. If however you want to run a server yourself just unzip all the files into your Kingpin directory and run the required command lines for Windows. (see below)
Configuring a server
There is one new server.cfg variable, BonusFrags. BonusFrags is the amount of extra points you get upon killing someone with the pistol, this can be anything from 1 to 5 points.
Starting a server
Windows - Run one of the two batch files, server.bat or dedicated.bat.
If you want to run a public server it's recommended that you also use the kpded2 Enhanced Kingpin Server file which is also available here at Gamefront.
