Hi, and thanks for the reminder – we've been meaning to clarify this message, so that's now back on our to do list! In the case of the campaign mode, it affects the whole save, so if you save a campaign with cheats enabled, you will no longer get achievements for that campaign. (Otherwise, it would be easy to just enable cheats, give yourself a million marks and all the upgrades, restart the game and cruise through collecting achievements.)
