Angry Birds 2 (Nopenop33)

Angry Birds 2 is a puzzle game released during 2015 after three years of development by Rovio Entertainment and published by ClickGamer before they were purchased by EA, since then it was run by Chillingo through version 1.0.0-2.2.0 before Rovio decided to self-publish the game for future updates on July 30 2015. Despite this developers from all groups are credited

Prototype Episode
The initial concept for the game came from an episode idea for the original game in 2012 however the developers quickly realised this singular episode (found in the original game’s files listed as ABEPISODES-9-ABISLAND.zip) would be too large to develop as a single episode and slowly was developed into its own game.

Most of the information in the .zip file has been removed however there is some information leftover that was likely left inside as they were reused for various purposes in the original game, these items are listed as follows:

ABISLAND-PIGPATROL-MOVER-MODELS-1/2.png
This pig is comprised of two separate models used as a solution for a walking Pig. They were cut in the final build in favour of an A.I. system and animation loop, the remaining image files are found on a Golden Egg hint in Angry Birds

ABISLAND-NEWEGG-WHITE/YELLOW-CURRENCY-MODEL.png and ABISLAND-NEWEGG-CURRENCYNOISE-AUDIO.mp3
When the files are activated in Angry Birds they default to being stuck off-screen while switching between the two colours on a loop according to the debug menu. The audio file paired with them is used when a player’s Mighty Eagle’s Mountain Level is completed, the reason the models are kept is due to the fact the audio can’t play without them. The same, albeit coded, version of the model and audio can be found in the files for Angry Birds 2 can be found, suggesting it was scrapped late in development.

ABISLAND-PIGCONVERSE-INFORMATION.txt
A string of code describing how a Pig would react to information given to them via a Walkie-Talkie altering their behaviour it was found in a separate folder known as ABHQ-TITLES-GPDEMOS.zip suggesting it was used in gameplay demonstrations and was accidentally kept in the files by an employee. This is supported by gameplay of the episode shown at Game Developer’s Conference 2012.

ABISLAND-NEWSPRING-MATERIAL-MODELS.png and ABISLAND-NEWSPRING-MATERIAL-FUNCTIONS.txt
These files are found in ABHQ-TITLES-GPDEMOS.zip as with the aforementioned assets, these ones, however, are actually used within the game, namely the new spring functions, the models are glitchy and unfinished so it is likely Rovio opted to simply use the new functions instead of the models.

ABISLAND-GLUEGUN-PARTICLE-MODELS.png
This appears to be an early solution for a Glue Gun Pig’s Glue Gun particles. It is added to a variety of models in the full game to make them look more complete, despite this, all of the originally functionality is lost. Despite this early footage of the episode from Game Developer’s Conference 2012 shows it would’ve worked almost exactly the same way as the final version, by connecting buildings together to make them sturdier if a Bird significantly damages it. If combined with Pig Conversation information it is shown to perform the action, (according to the debug menu) however the information necessary for it to work has been lost.

ABISLAND-ELECTRICDEATH-ANIMATION.mp4
This animation would play if a bird was hit by an electrical object. It can be used if it is combined with the Pig Conversation information and glue gun particles, despite appearing to not play animation, the debug menu shows all ABISLAND death animation files play for a split second before being replaced by the normal death sprite as the game doesn’t recognise the projectile that has hit the bird and so reverts back to the normal sprite.

ABISLAND-GASDEATH-ANIMATION.mp4
As with the previous file, if combined with some remaining assets it can play, however it will revert to the default sprite before it can be seen.
