Angry Birds Go! is a kart racer built off Exient's XGS engine. What could go wrong?

Internal Project Name

The game assets, CDN url, and library code mention Yellow but also mention ABK and XXX.kart. The project name was likely "Angry Birds Yellow" or "Angry Birds Kart".

Debugging Utilities

To do: Enable and show these on in version 2.8.2.

Debug Menu:

A Debug Menu is present in the game files based off xml/xml.pak and library code.

• 
  Go to any enabled screen: Goes to any screen in the game as long as the file(s) is/are present and library code has FE in the name of the screen,

• 
  Change Locale: Changes locale to a new one, also can use String IDs, the current is displayed by the CURRENT value.

Debugging functions are also present but is currently unknown how to enable.

There is a call for loading the developer menu, but the file isn't present (or in the application library?) so it's impossible to load (without editing XMLs(?).

Debug Tweak Table XML:

A debugging feature tweak table is present in gameplay/misc.pak/ and is named: DebugTweaktables.xml. It has a LOT of tweaks that are enabled (aside from true debugging tweaks) on every game bootup, even for a retail build, some code isn't present in the library and/or the XML.

Sections are also present, including DebugTweaktables to start it off, Camera (In-game Camera), Rendering (GUI), LensFlare (Lens Flare), Stats (Rendering/Performance Status), Bloom (Bloom) BossBattle (Boss Battle), Gameplay (Gameplay), Powerup (Powerup configuration), Car (Vehicle), Audio (Audio), Controls (Controls), HUD (HUD). Misc (Miscellaneous), Energy (Energy), Timings (Time), ReviewNotification (Review Popup settings), GemOnlyPurchases (Gems only used for payment), DifficultyAdjust (Difficulty), QMR (Quality Management Representative settings), FTUE (FTUE settings), LocalMultiplayer (Local Multiplayer settings), Store (IGC price), UI (UI) and Connectivity (Network settings).

Unused playable characters

To do: Show these characters in game.

Minion Pig: In the character icon image ui_core.pak/textures/uicharacters_1_of_1.xgt, there are complete icons for a Minion Pig for both the character select (or daily challenge popup) and in-game avatar (that the AI uses). There are also most sounds for them meaning Rovio was likely planning to make it possible to play as one, the character's script file is characters/charxml.pak/char_015.xml and it disabled the character as its instead used an AI rival. The character uses some of Foreman Pig's code, also used Red's ability icon for the ability icon.

Dealer Pig: In one of the character script files: characters/charxml/char_015.xml, there's a mention for Dealer Pig and it disabled the character for some reason, it is partially based on the unused/AI Minion Pig and also used Red's ability icon, there are no plain icons or sounds for this character.

Leftover Version 1 assets

A ton of assets are left over, including textures and more.

Unused computer DRM activation

The game was likely planned for some time to computers (or Steam) but it was cancelled likely for the favor of mobile devices, the game library mentions PC DRM, including the DRM server URL, links and protocols.

Developer notes

In many XML files, there often are developer notes for setting up the XML assets, one goes by: CUP (awaiting design), another goes by: Workshop no panel required, should link to upgrade screen and possibly many more.
