The Rusty Walrus Chase is the second chase level in Crash Twinsanity, in which Rusty Walrus chases Crash in N. Gin's battleship. Rusty is invincible to all obstacles in his path. Hazards include nitro crates, pits, TNT and fire. Crash must reach the end of the two long corridors, avoiding the obstructions and staying ahead of Rusty. If Rusty catches up to Crash, he will die and have to respawn at the last checkpoint touched. There is a checkpoint at the start of the first corridor, another at the start of the second corridor, and one at the beginning of the N. Brio and N. Tropy boss fight which follows on from this chase.
- The music that plays in the level is based on a classical song known as 'Hebrides Overture' By Felix Mendelssohn.
- The take Cortex everywhere glitch allows the player take Cortex into the level, making it much more difficult.
- There is also a glitch to make the chase scene easier. After the cut-scene that plays via entering the chase scene, quickly spin the wall behind Rusty. If this technique is performed correctly, you will end up behind him.
