LEGO Island 2: The Brickster's Revenge is a rather rushed successor to the popular LEGO Island. This game started as a tie-in to various product lines from LEGO, headed by Krisalis Software. The developers couldn't scrap their work, so no one noticed the main character looked a little like Pepper Roni. Development was then tossed on over to Silicon Dreams, who then tried to hack it into a LEGO Island game, but the project turned out a little too ambitious and it ended up being a case of planning too much without seeing.
The result is a very obviously unpolished game with long load times, hacked together story and gameplay, and voice talent that was all done by 5 people. Although not a downright horrible game, the best way to describe it is what Pepper says when he gets off of his skateboard.
On the plus side, though, this also means it's rife with unused content.
There's quite a bit more unused stuff, notably some extra text and possibly textures.
This is an unused area in the Pyramid Area of Adventurers' Island, after the Snake Pursuit but before Desert Speedster/Fishing. If you get the camera at the right angle, you can see inside the pyramid revealing an unused area. It's a small hallway with four pillars and a room with a coffin at the end. The hallway is just behind the pyramid's door, which is more of a decoration rather than a real door since it never opens up.
Through the methods shown in the video, you can get inside it, the area is pretty much empty though. It's unknown what it was going to be used for.
An unused music track found in the game's files called "Town Bridge" plays a short lighthearted introduction, plays all the way through the main theme of LEGO Island, and awkwardly transitions into a strange lower-pitched segment. The last segment can be found individually as "TromSolo", but it isn't used either.
In the original soundtrack, the title track includes both segments in succession before looping back to the main theme, suggesting Town Bridge and TromSolo are leftovers from when the OST was converted to MIDI and just weren't reused for anything in the game.
An alternate version of pulling out the skateboard, followed by an excerpt from Apocalypse Now: "I love the smell of napalm in the morning!" This is stored in the folder with T-Rex Racing, obviously left in by mistake considering the file name. The video on the right showcases what this sounds like in-game if the existing skateboard sound is replaced with the unused one.
Nearly every single piece of dialogue is subtitled in the game's files, regardless if the dialogue is part of a cutscene or not. This includes all the grunts and all of the minigame banter, which are normally played without subtitles in-game. In most cases, the subtitles are exactly as one would expect, but one particularly noteworthy exception is that in the Snake Pursuit minigame, Johnny's line "Another gem gone!" is bizarrely subtitled "Damn, another gem gone." This never shows up in-game, but it's still a bit jarring to see mild profanity in a game for children. The reason of this is unknown, even though it's likely due to an angry developer who was going crazy with the subtitles.
