Hi!
i would suggest to add a FlameThrower skill to the server.
the player who chooses this skill he get the FlameThrower weapon.
his job happens when he type in the cmd: /flamemission1,0 (/flamemission1=turn the flamethrower mission on,/flamethrowermisssion0: turn it off)
when he types the command he need to go and burn some crops/trees/etc.
for each five crops he gets 9000$,+1 score and +1 flamethrower level.
if he burns players to DEATH! he will gain 18000$ and +2 scores +2 flamethrower level. (double the budget)
he will first start on a Molotov cocktail on level 20 he will get the flamethrower and will get 5000$ but no score.
on level 50 he will get 10000$ but no score (all the next flame thrower skill level the player will continue with the flame thrower weapon.)
and on level 70 (max) he will get 25000$ and +2 scores.
to see your flame thrower skill level,type the cmd: /flamelevel

maybe getting money is bad idea but anyways.
Hope you like my idea.
Thanks For Your Support.
