I like Archsteel's idea of a guard impersonator, and also Admiral brought up the idea of converting Storage C(office) Guard Spawn(Mansion) and Container(Camp) into a monitor room. Guards going in there would be allowed to go spectator mode, except that he views the item locations instead of the players. Would also be useful for newbie players learning where the items are.
Top tip for guards: Never open the door to an unlighted room without instantly checking the sides of the door.
Top tip for thieves: Never try to fight a guard one on one unless you're sure you can win(eg. cobra stab, guard is wounded)
"I've come in to get my badge of the day. I don't usually play platformers, so I bet this one will be as bad as the others. I'll just get my badge and lea-"
Wait, what? Is that a cowboy cactus?
Very easy way to farm money-tickle the buddy until he gets so much happiness that he gives you money. By then you should have lots of cash. Use it to buy explode at mouse. Explode at mouse gives the best money in the game. flamethrower and molotovs are also good.
A tip on Conquer mode:Don't go all out and attack enemies immediately! Focus on expanding your territories. Many players make truces with each other to prevent early fighting, which benefits nobody except the ones who sit out hte battle and then gobble up the weakened fighters.
