Big Money and Better Weapons
Go into the guns.ini in the data folder of the game's directory.
Once in, change all the gun prices to -999999. Make sure that you change all the guns to the same price!
Then start game, select tournament mode {go through choices until you get to the Manage Team screen} pick one player and accept. Then go to the Buy New Equipment screen. Then go to the Markers screen and buy any gun and you will recieve the diffence in cash back. Do this for each player you select for your team.
Also, if you want to switch to another gun later on, it should cost you zero dollars. Now, for the guns: while in the guns.ini, you can adjust the settings of each gun. The spin velocity, muzzle velocity, shots per second, reload quantity, air, auto, and scope {play around with numbers until you "tweak" your gun the way you want it}. Example: If you change the "0" to a "1" on the "auto" line, it will make that gun fully auto.
Note: you can't have auto and grenade on the same gun. It could lock up the program or you won't be able to shoot anything---paintballs or grenades.
