I'm adding in an additional 20 achievements in v3.0.0 (bringing the total number of achievements to 45). Below is the full list. Bonus points if you want to work out the many references in the names, they're not very subtle
There are also 6 new "cheat" passcodes that will be revealed in the Episode III epilogue, so there are now 16 cheat codes that all have varying effects on the game (eg. disable wall clipping, no enemies, fast enemies, reversed direction controls, etc.)
Also the Security Guard enemy from ABIV has been reimplemented.
