Hint: Get Mini Cons at Research Center
before fighting Starscream:
Instead of going down between the hangers, walk around
behind them. If you do not walk in front of Starscream's hanger,
he will not come out. Blow up the buildings with rockets. Some
of the buildings contain Data Cons. Three of them contain Mini
Cons. One of them can be especially helpful against Starscream,
as it is the one that constantly restores your energy.


Hint: Defeating Starscream:
It can get difficult to kill Starscream beacause of
all the enemies around him. Using the sniper rifle Mini-Con, pick
off enemies before facing him. If you are discovered, jump back
into the portal and save the game. When you come back into the
level, there will be less enemies. Repeat process until there
are no enemies remaining, then face Starscream.



Hint: Faster gliding:
With the Gliding Mini Con, go to a level in a big space.
Press L1(2), X very fast.
