I have been receiving a lot of reports that there are problems with the game’s official launcher. The architect of the launcher, NoxCaos, has recently made some changes in an attempt to resolve the problem. A new version of the launcher is now available. If you were encountering problems when attempting to use the launcher in the past, please download the latest version here!
There is also a new build available tonight, with just one bug fix. Previously, in Mission Mode, if the player chose to play a mission featuring Nemesis wearing a randomly-chosen disguise, there was a chance that Nemesis would choose your target for her disguise, which would make the mission unbeatable! Whoops! That bug has now been fixed; you can download the latest version of the game to get the fix.
If, for some reason, the launcher fails you, then you can download the game from any of these other sources:
