Lego Mars Mission: Crystalien Conflict

In 2007, Lego launched it’s Mars Mission themed line of Lego building sets. The sets focus on a conflict between human astronauts and Martian aliens over Crystals, a new source of power found on the planet. To help market these sets, and to provide a fun activity for those who like the setting and story, a game named Lego Mars Mission: Crystalien Conflict was created. While this free online game is fun, it can at times be quite difficult. Here are some cheat codes that can be entered on the main title screen to help give you an advantage!

Cheat Codes

These codes are entered on the main title screen of the game. There is a box in the bottom which allows you to input text. Note that when typing, it will convert your key presses into an alien font (there is a download link for this on the page, if you want to play around with it on your computer!), so pay close attention when inputting these codes. When a cheat code is entered successfully, you will be notified with an audio clip and text stating what code you entered. If unsuccessful, it will display ‘Access Denied’ and allow you to try again.
