Defender - Platform: XBox

In-flight mechanic:
-------------------
In some levels there are little tank-like units that remain stationary. 
These are the units that shoot out the lightning and repair structures. 
They cannot move on their own, but you can pick them up to place them anywhere 
and they will slowly repair any nearby units or structures. If you pick one up 
and fly around with it, whenever you take on damage it will fix your ship. Be 
careful though, because any enemies that may shoot at you from below could hit 
it, and they cannot repair themselves. However, sometimes it better to leave 
them near your base so they will repair things as needed.

In-flight artillery:
--------------------
If you need a little extra firepower for your ship, look for a tank and pick 
it up. As long as you are holding the tank, it will act like a rotating turret 
for your ship and fire upon any enemy units that get within its range. The tank's 
cannons will rotate 360 degrees so it can attack enemies all around you. This is 
very useful if you do not want to deal with having to make constant maneuvers to 
avoid being hit by an enemy that is tailing you.

Faster weapon recharge:
-----------------------
You can make weapons that are rechargable recharge faster when you get the 
power-up by holding A for about five to ten seconds. Release A and your weapon 
should recharge faster than normal.
