To find princess lia all you have to do is go to free the slaves and any thing like those small doors make somebody small go through and thentry every thing it took me about 4 hrs to complete the game and I got han solo for more hints or cheats on any game on ps2 or wii I am your guy my email address is laokang@hotmail.co.uk no capitals I am a fan of mortal kombat the name Zephaniah

It helps some in this game if you watch the movies that way you would have a better idea on how to beat the levels.

To find R2D2 go to Desert Ambush, get the horse, go to the other side hit X and the horse will launch you up, go to the top if you didn't get the artifact get it, go back and become Indi use your whip pull down the bar and R2D2 should come out of a tube.

To find Luke Skywalker, go to Into the mountains, once you get farther in a ice bridge will colaps, go to the bottom and take a bazoka trooper blow up the the glass, go in and you find Luke Skywalker

Ok this is more of a glitch then a hint but theres not a glith submission so you know. Ok on the level of raiders orf the lost ark (into the mountain level)were theres the snow part and the building on fire go in free play and choose a guy that is in army with a black hat and go to that snow part where the whole building on fire ok so get you're army guy and knock on the building that the enemy army dude lets you in pull the rope and do some stuff like destroy everthing and al the puzzzles in the room and if you look closly at the fire santa will come down and go out of the door it's funny!
