So, we start off at first story level right away. Immediately quit out and go to the room where you enter the cheat codes (it should be the second one on the left) and enter everything you feel that you will need. I do not recommend unlocking the characters since you can miss one and that one is not unlockable by any cheat I found so far. So, after you've entered each extra code you will get the following achievements after you entered the very last code.
Head into the garden (first door on the right) until you reach the end of it and create a custom character. Rename it and after you've done that and you will get another achievement.
Now head upstairs where the mission select is and move to the right. Place the crystal on the plinth and the achievement should unlock. you can unlock the bonus levels in this room after you get all of the artifacts in all levels and you've used the key on the keyhole underneath the plinth. You get the key in the room next to the garden entrance, simply use the corresponding characters. If they dont spawn near you, simply go to any mission in freeplay, choose the character and quit out after it has loaded up.
When you have done that start at the very first level again, activate everything you feel comfortable with using and go on through the story. The levels are straight forward and if you are familiar with the movies you shouldnt have any problems in completing them. I've posted the order of the levels and the achievements you will get over the course and point out special levels where you can get specific achievements. In case you get lost, I've posted videos I found on the internet. Credit, of course, to the publisher of the videos.
That concludes Act 1 of the game, Raiders of the Lost Ark and nets you a fair amount of achievements.
Now we will start on Chapter 2, Temple of Doom. I won't go into detail since the levels are always straight forward but again, I'll post the videos here.
Now that you have finished adventure number 2 we can go for number 3, "The Last Crusade". However, as soon as you get both Jones' (young and old), defeat each other. You need to beat the young one with the old one for the achievement to unlock.
Complete the "Trouble in the Sky" level in Story Mode.
Congratulations, you have now finished the whole story and can go now for the remaining collectibles. Don't forget to go for the Star Wars characters for the last hidden character. The description is on the collectibles list. After you've got everything you can finally enter the secret levels, but don't forget to buy the "Lao Che" character for the following achievements. Simply beat Indy with him and vice versa.
Now we go to the level where you escape by train. This is by far the easiest level to go for the following achievement, just kill the first guards carefully and DO NOT use the invincibility since it will void the achievement. Use one of videos above for details on the level.
On the level Pankot Secrets you can get the following achievement. Simply choose a Rocket Trooper and kill 5 spiders in one explosion after you get across the bridge over the river.
You can either do this in Story Mode or Freeplay. I did it in Story Mode and basically the thing you will have to do is to grab your female partner (you get a new female character after each adventure) with your whip. If you do it correctly you will kiss her and as soon as you've kissed all 3 of them (Marion, Elsa & Ripley) the achievement will unlock. You can also do it with your second controller taking place of the AI since they tend to wander around.
Now that you have collected every artifact you will get the following after the last one. After you've unlocked the last characters, you get another 2 achievements on the way.
The following is actually for beating the bonus level "Young Indy", which is the very first one to unlock. It's not too hard, so no need for explanations here. However, I found a video for it as well.
Now the last ones you will need is the grinding ones and the 1,000,000 in the Secret Temple level. I did a walkthrough on the level in my collectibles list, so use that one to finish the level in no time.
Congrats, you now have a full 1000!
