World Wide Webbed
From Hungrysoftware
The second official expansion pack for Ducks, but the first huge official pack featuring forty new levels accompanied with new images and sound. Due to no new objects being added, the levels present a much more increased difficulty than the main levels, thus not being for the novice players. World Wide Webbed is currently unavailable to buy since the Hungry Software store is temporarily broken and its license status is unclear whether the creator will release it for free or will keep selling it.
This pack is also notable for the first time inclusion of episode preview backdrops (as seen in the right picture) when previewing a level. Although version 1.2 of the game introduced this feature, it was not revealed until this pack extensively used such for its four episodes.
Since the expansion pack is exclusive to registered users, a four level demo is available for registered / unregistered users as a taster of the new levels.
