LEGO Batman: The Videogame Cheats (PSP)

To unlock Arkham (psychiatric hospital for the criminally insane) you must achieve 'True
Villain' status on ALL levels in the Villain storyline by collecting enough studs to max
out your stud counter on each level. To access the villains and the level go to the right
of the Batcomputer and down the ramp and pull the lever. Then go through the door on the
right to reach the Memorabilia room where you then climb the ladder at the top.

These characters become available for purchase for the indicated amount of studs at the
Batcave when you have completed ALL 3 chapters in the game and viewed the end credits. 

Unlock Huntress: Complete the game and purchase for 200,000 studs. 

Unlock Azrael (Angel of Death): Complete the game and purchase for 1,500,000 studs.

This feature becomes available when you have completed ALL 3 villian chapters. The villain
chapters are accessible from Arkham Asylum.

These two characters are unlocked when you beat the game with the corresponding task
completed.

Unlock Hush: Rescue ALL 25 civilians in the game. To find out which levels you still need
to rescue a civilian look for the small face with either a happy or sad face indicating
whether or not you still need to rescue them.

Unlock Ras Al Ghul: This villain whose name means 'The Demon's Head' is unlocked when you
have collected ALL 300 of the mini kits. There are 10 in each of the 30 levels.

The following codes are entered at the computer in the Batcave or the hacked computer in
Arkham Asylum. Remember that unlocked characters are only available in Free Play mode.

alternatively achieve 'Super-Villain' status on each Villain mission. To reach these
statuses you have to collect enough studs to max out your stud counter on each level. To
access the mission go to where the vehicles are in the Batcave and then go to the far
right and down to the bottom. Step on the elevator which will take you to the Memorabilia
room and the Wayne Manor mission is in the upper left corner.
