I just though I'd post a little how-to on unlocking all the levels in the Single Mission menu, and how to play an adventure game starting from any level.
Unlocking All Levels in the Single Mission Menu
1. The first thing you'll need is a copy of the game's first mission file "M1010.PUZ". You can either extract it from the 'Etc.pac' file using my PAC Extractor: http://www.rockraide...ith-all-option/, or you can simply download the file from here: http://www.mediafire...irxfw/M1010.PUZ
2. Once you get a hold of the file, you'll need to put it into your 'LEGO Alpha Team' folder (the same folder that contains 'Etc.pac' and 'LEGOATeam.exe'. The path should be something like "C:Program FilesLEGO MediaGamesLEGO Alpha Team")
3. Now you want to open "M1010.PUZ" with a text editor (Notepad should be fine, just make sure you don't use a rich text editor like MS Office or Wordpad). Towards the end of line 7 should be a bit that says "Portal=M1020", we want to change the "M1020" part to "M4070". Once you make this change, save the file and close the text editor.
4. Finally, launch the game and start a new adventure (you can skip the briefing and the training mission). Play through the first mission, once you beat it and click to go to the next mission, if you modified your "M1010.PUZ" correctly, the final level of the game should load. Play through the final level. Once you beat it and skip through the credits, all the missions in the single mission menu should become available to play.
Start an Adventure from Any Level
1. This is almost the same process as above. Follow the first three steps to get "M1010.PUZ", place it in your 'LEGO Alpha Team' folder, and open it with a text editor to change "Portal=M1020" on line 7. However, instead of changing "M1020" to "M4070", we need to change it to the level we want to start our adventure from.
2. Here's a list of the code names for every level:
3. Launch the game and start a new adventure (like I said above, you can skip the briefing and the training mission). Play through the first mission, once you beat it, the level who's code you put in "M1010.PUZ" should load. You can now play the adventure like normal.
