Wow! Third island, you've beaten the muscle mountain Koala Kong! Hurry, Tawna needs your help! - Level description
Heavy Machinery (きかいか けいかく lit. Mechanization Plan in Japanese) is the eighteenth level (including boss fights) in Crash Bandicoot and is the first level of Cortex Island, as well as the first level of the Cortex Power Refinery side. It features both a Tawnabonus round and an N. Brio bonus round. It has a secret area where Crash can jump down a gap guarded by two robots near the start of the level.
The level is a welcome start to the heavily industrialized Cortex Island compared to the other islands. As the name hints, Heavy Machinery is situated inside a large factory with many mechanisms such as boiling pipes (which can burn Crash) and cold pipes, conveyor belts, and spring platforms, overseen by various robots working for Cortex. One robot crawls along the floor while another spiked robot floats in the air. There are also Hologram Probes watching the bandicoot. Toxic waste can be seen in drain pipes on the wall in the background.
This is the first level in the series to feature robots.
During development of the game, this level was the first successful one. The second being Generator Room.
In the prototype, Heavy Machinery is the second level of the third island instead of Cortex Power. Also, the hologram probes had not yet been finished and appear as floating orbs. They will still harm Crash if he touches them. The probes also appear like this in Generator Room.
In the prototype, the gap that Crash can fall into to break open some crates acts as a shortcut through the level. The shortcut takes Crash up to the point where he acquires a Brio bonus mug and extra lives.
