Are there any cheats for this game?

I just heard a rumor that an X-Wing can be unlocked by completing all challenges.

I just beat the game and unlocked the X-Wing and TIE Fighter for "instant action" mode. I think to unlock them you must beat all challenges and/or all campaign missions. Not too sure wich way it is, but I beat all challenges before beating the final mission. Man those Star Wars crafts are fast! They go close to 1,000 mph! That's faster than sound (wich is about 762 mph)! Plus they never run out of ammo!

So, are there any cheats for this game? How do you get past the first mission on the Eastern Front? the one with all the tanks

No actual cheats that I know of, but Lucas Arts is notorious for putting cheats in their games. To answer your question do this:
Scout ahead and destroy every Panzer tank you see.
Then destroy the anti-tank guns.
Around this point Lilia spots Bf110s and calls for more fighters. There are also Stukas. Select a Bf110 and tell your team mates to attack your target, and you head for the Stukas. Shoot down the Stukas.
Head for the Nazi airfield and destroy the hangars.
Keep shooting down Stukas!
Bonus****************
Destroy train (useing machineguns).
Destroy ALL AA-guns!
*********************
Finish off the huge bomber with both rockets (or 57mm cannons) AND your machineguns.

I don't know what's wrong with these other guys but these cheats work.

They don't work. I tried them at slow, medium, and fast speeds just to be sure. They don't work. No confirmation noises, nothing.

The Codes do work (except for God Mode for some unkown reason) the main screen is the New Game, Continue screen that's where you enter the code you will hear "Secret Code Accepted" or something like that, hope that helps

Ohhhh...alright, I'll try that; It better work.
