Crash Twinsanity - The Bug Run
Another prototype uncovered by Jon Burton, this one contains quite a bit more content and a few updates compared to the December 2003 build. You'll notice, for example, that even though the HUD still has words instead of icons, the font is now a faithful recreation of the same one used in the original PlayStation era, as opposed to the entirely new one used in the final version. The E3 2004 demo uses this same classic font, so it was replaced fairly late during development.
Additionally, an entirely removed area can be found in this prototype. See, in Jungle Bungle, there's a seemingly redundant picture of a tribesman bouncing off a worm just before Cortex teaches you how to do it. The picture is there because this path used to have a divergence on the left, with a second picture indicating what you could expect there (as seen above).
The Bug Run, as it was internally nicknamed by the developers, was an optional route where Crash would go underground and be chased by a myriad of bugs in a typical scene where you'd run towards the camera. This should sound familiar if you've played the level Classroom Chaos, since the bugs were eventually moved to Cortex's part of that level. The reason this segment was cut is because it was much too difficult.
Jon Burton, founder of Traveller's Tales, has posted a video of this section as found in a prototype. This particular prototype doesn't actually feature the bugs themselves or even a fixed camera angle, but it gives us a good idea of what it would have been like.
The Entrance
Upon taking the route to the left, you'd find a large hole in the ground that led to a tunnel, followed by the ruins Crash would run through while fleeing from the bugs. It's interesting to note that while this entire section was limited to the hole itself in the December 2003 Prototype, the darkness in this prototype would lead you to believe there's nothing inside the hole in this prototype either. Jon was forced to turn up the brightness in order to even see the tunnel.
The Course
The actual course is a dark place lit only by gaps in the ceiling and bioluminescent mushrooms. It's a typical passage filled with ruins with various objects for Crash to circumvent, encompassing stone blocks, pillars, and pits.
The Exit
Just before reaching the exit, there was a very large gap that Crash couldn't jump across. As Jon suggests, there may have been some platforms implemented there later on, and the bugs might have fallen down the pit. Once you cleared this gap, you'd reach a wide tunnel with some steps that led you back outside. Curiously, you'd end up in the other side of where Cortex and the worms are (in the final version, this small area just has an explosive crate row with a gem and a statue identical to Tikimon). This means that despite all your efforts, you'd still need to play the rest of the level as usual, suggesting the Bug Run was going to have some sort of optional reward, most likely a gem.
