Hint: Easy money:
Find any mission that has an advance payment. Start the mission and immediately 
abort it. After this is done, you will see your earnings displayed in two boxes. One 
box is for your new money amount that was earned and one for the deductions for 
repairs, ammunition, and the special deduction in the event that something was 
destroyed that was not supposed to. Note that there is no deduction, and you will 
get the amount that was promised to you in advance. Make sure to save your 
game before you do this, as the game will end if this is done too many times.

Easy Arena wins:
Select the Trene City area. When the battle begins, there is a big building directly 
in the middle of the Arena floor. Boost up to the top of the building and pummel 
the opponent AC full of rockets or other types of ammunition that can lock on. If 
you are unable to boost up the entire way, there is a ledge halfway up. Rest there 
momentarily, then boost the rest of the way. Weapons that are the most effective 
are the small rockets and/or vertical missiles. There are some enemies that are 
too fast to do this to; they move to much to get a lock on. If this happens, when 
you start, boost West and position yourself in between two buildings very close to 
the border. Most of the enemy ACs will not go behind because they will lose. They 
will just move back and forth trying to get a fix, but will not approach you if you 
are very close to the border. Pop in and out from behind the building and shoot 
various rockets and missiles as the ACs are moving around. It is slightly time 
consuming, but a very easy way to boost ranks early.

Take your opponent to the Arena stage. Have Hectos Rockets and the left hand 
grenade launcher equipped. When the battle starts, start stepping backwards, 
making sure not to turn or alter where the aimer is pointed. Switch weapons to the 
Hectos Rockets and keep firing those with the grenade launchers. The opponent 
will just follow your steps, and will not move from the line of fire. If they get too 
close, start to fight normally; they will have low AP at this point.

Hydraulics:
Get a robot with the tank wheels. Press X repeatedly and it appear as if 
the robot has hydraulics.
