The Extended Project in general is about extending the game, fixing issues, expanding the story through added levels and lore. Serious Sam 3: Extended Part 1 is kind of a black sheep when it comes to that: I add no new levels, but change the old ones to play a lot better, with a few new added extras, like secrets, traps, trapped secrets or even a slightly extended ending. Part 2 however, will include new levels, as soon as it is available.
