Once you've beaten all five levels in this hub in Story Mode, return to the hub and locate the entrance to each of the five Treasure Mode levels (shown here).

Complete all Bonus Levels in Skull 1 Hub.

Each hub contains five Bonus Levels plus one Super Bonus Level. The entrances to the five regular Bonus Levels can be found in the hub. (See here for specifics.)

When you have them all, smash them and use the pieces to build a special LEGO model, which will enable you to enter the Super Bonus Level.

10 

I taught you self-reliance.

Complete the Builder Tutorial levels.

If you haven't already done so, complete the Kingdom of the Crystal Skull Part 1 in Story Mode to unlock the Creator hub. Open it and select Level Builder. Then select the tutorials in the first drop-down menu. Follow the instructions to complete all four tutorials and unlock this achievement.

15 

Wiped clean by the wrath of God.

Edit a Bonus Level in the Builder.*

Unlock the Creator hub and complete the Level Builder tutorials as described above under "I taught you self-reliance."

20 

Seeing communists in our soup.

Defeat 50 Russians with Mutt.

This can be done in various ways, but the easiest are to play as Mutt in the Crystal Skull Part 1 or 3 hub, locate one of the Russian soldiers (unlocked after completing the Treasure Mode levels) and smashing him repeatedly until the achievement pops, or just keep replaying one of the levels where Mutt fights Russians (e.g., Cafe Chaos or Mac Attack).

15 

So what are you, a triple agent?

Destroy Indy 3 times with Mac.

Enter the Crystal Skull Part 1 hub, select Mac and use him to smash Indiana Jones three times. Quick and easy.

15 

"You're a teacher?" "Part-time."

Use Scholar access 10 times.

Scholars are characters who carry books that allow them to solve the hieroglyph puzzles found in certain areas. You'll do this as you play through the game but probably not enough times to unlock the achievement. So either replay levels with glyph puzzles (e.g., Venice Library, one of the Last Crusade bonus levels) or create a custom level with multiple glyph puzzles in it and play it until the achievement unlocks.

15 

Obtainer of rare antiquities.

Find all the Artifacts in the game. (Single Player Only)

Artifacts are the golden treasure chests found in the Treasure and Bonus Levels. There are 5 Treasure and 5 Bonus Levels in each of the 6 hubs, and one chest in each of these levels, so 60 artifacts in all. (See the level walkthroughs for details.)

75 

I'd cover my ears if I were you.

Fire a Bazooka 100 times.

You'll make some progress toward this achievement during the normal gameplay, but if you fall short of the goal, just unlock a character who uses a bazooka (see the Characters page for details) and spend a little time in one of the hub maps blowing things up.

20 

Not as easy as it used to be.

Complete Hangar 51 in under 5 minutes.

"Hangar 51" refers to the 1st Story Level in Kingdom of the Crystal Skull Hub 1. It is technically called "Hangar Havoc". You'll need to beat this level in Time Trial (i.e., replay it through the hub menu, as shown here) in less than 5 minutes. This can be quite a challenge. It helps a lot if you use 2 players and have enable the Fast Build and Invincibility Extras beforehand. Or try it in Quick Play mode using characters that carry a spear and a Staff of Ra. For tips, visit xboxachievements.org.

25 

You know how to fly, don't you?

Complete all plane races. (Single Player Only)

There are 6 plane races—one on each hub map. The location of each aircraft is included on the Vehicles page and in the hub walkthroughs. Once you've found and purchased each plane, get in and fly up to the starting gate for its race. Follow the course to the finish line, flying between each set of markers, within the time allotted to win the race.

35 

Wow! Holy Smoke! Crash landing!

Destroy 100 enemy vehicles.

You'll probably unlock this achievement while playing through the Story and Treasure Mode levels, but if you fall short just replay the vehicle levels as needed.

25 

Do svidanya, Dr. Jones.

Destroy Indy with Spalko.

After completing the Crystal Skull Part 3 in Story Mode, you'll be able to purchase agent Spalko. To get her, go to the foot of the temple stairs (the exact spot is shown in the hub walkthrough), dig her up and purchase her. Then use her to smash Indiana Jones to unlock the achievement.

15 

What are they? Spacemen?

Unlock the Interdimensional Being. (Single Player Only)

After completing the Crystal Skull Part 3 in Story Mode, you'll be able to buy the UFO Ride, which is located near the bottom of the map.

A long time to wait.

40 

Now you're getting nasty.

Unlock all of the enemies in the game. (Single Player Only)

You'll need to unlock and purchase all characters to get 100%, so this achievement should unlock in the process. If you're having trouble finding certain characters, check the hub walkthroughs.

40 

Get on, Gramps!

Unlock all of the vehicles in the game. (Single Player Only)

You'll need to unlock and purchase all vehicles to get 100%, so this achievement should unlock in the process. If you're having trouble locating certain vehicles, check the hub walkthroughs.

You choose the wrong friends.

Complete all Story Levels in Quick Play mode. (Single Player Only)

After completing each hub in Story Mode—or later, when you've finished the whole game—go to the Creator hub, choose 'Quick Play' and replay the Story Mode levels (i.e., just the first row of 5 levels in each group). You do not have to replay the Treasure or Bonus Levels.

50 

No defiant last words Dr. Jones?

Complete the game to 100% (Single Player Only)

This is the big one. Basically it involves completing each of the 7 hubs (6 story hubs plus the Creator) to 100%. To do that, you must do the following:

• Complete all Story, Treasure and Bonus Levels (15 levels in each of the 6 main playsets).
• Unlock and complete the Super Bonus Level for each playset (6 in all).
• Earn True Adventurer status on all levels (except the Super Bonus Levels, where this is not possible).
• Unlock and purchase all characters.
• Unlock and purchase all vehicles.
• Find all red, green and blue bricks.
• Purchase all Extras.
• Complete the Creator playset to 100%.

NOTE: Completing the first 7 items in the list above should result in 100% on the 6 main playsets. To achieve 100% on the Creator, complete the 4 Level Builder tutorials and purchase all available objects in the 7 playsets within the Builder. There's no need to create elaborate levels here. Just buy everything, save and exit. The achievement should then unlock. (The Creator page has more details.)
