Here are 11 tips i have concocted from experience with the game
Tip 1: Capture as many unlucky souls as you can, sit back and gloat at your impenetrable trap network!
Tip 2: Never make a hotel, its alot of money wasted on a cover show that never lasts, when the big boys show up they will turn your hotel resort into a battlefield!
Tip 3: Be an absolute dick, it comes with the job of being short and evil >=D
Tip 4: The henchman Ivan has a bazooka great for crowd control.... use him cautiously indoors...
Tip 5: Valets are good for one thing, disposing of corpses, other than that you will only need them for missions
Tip 6: Get all the loot you can, it gives your men super work ethic!
Tip 7: Fire can be your friend, but more likely your enemy, if you do plan on placing fire traps keep a whole lot of fire extinguishers and technicians ready, you will need them!
Tip 8: Combo traps, you gain super awesome points if you link your traps to others, as an example think of a giant fan blowing you into a piranha tank!
Tip 9: Valets always set off traps, so don't keep to many running around, upgrade them ASAP
Tip 10: Yellow Alert, its your best friend, play the game on this mode constantly, your men will equip themselves with guns and nades and head out killing anything you tag!
Tip 11: RED ALERT, for the last hour of play this button will be your best friend >=D
