Angry Birds Space Assault!

Angry Birds Space Assault! is an unreleased game by KLab America which was planned to be a spinoff to Angry Birds Space. It was described as a "3D action strategy collectable game".

Gameplay
It was planned to be played a similar way to Angry Birds 2 with cards, the main difference from the other games is that it isn't primarily a slingshot game, as the birds had a ship that you could fly around the level to solve puzzles. The pigs also had their own defenses littered throughout levels that could damage the birds' ship if not destroyed quick enough. Some of them also block the way and when destroyed unlocks new paths for your ship to travel to. Eggsterdoids were also planned to be in this game but as regular collectables that you would have to solve puzzles to get.

Trivia

 * Around May of 2021, the creator of the project Glen Dahlgren took to the comment section of his upload to ask how so many people found his blog post when he had admitted the article was unfinished. He is quoted as saying, "It's amazing that people are finding their way here."
