Crash Crush (ゆきだま スライディン lit. Snowball Sliding in Japanese) is the ninth level and is the fourth level of the second warp room in Crash Bandicoot 2: Cortex Strikes Back and the Crash Bandicoot N. Sane Trilogy remaster of the second game. It is a sequel of sorts to Crash Dash, in which Crash is again tasked with running away from gargantuan snowballs during the evening. Crash still has to dodge mines and electric barriers, but this time he is assisted by turbo pads scattered around the stage. Players will have to make efficient use of these turbo boosts on the final snowball run, as it contains a locked crate that Crash won't have enough time to belly-flop open unless he has a significant lead over the snowball. Shortly after the first checkpoint, there is a brief split path Crash must take if he wants all the crates.
In this level, nitro crates are destroyed by the snowball, and there is no nitro switch crate. The problem is that it's possible to get very far ahead of the snowball and so if the snowball running over the nitro crates is outside of the range of the camera, then they won't be destroyed. Therefore, if Crash is very far ahead of the snowball, he must wait to see it hit the nitro crates, in order to get the gem. For whatever reason, this warning is not stated in most walkthroughs of the game.
As with the other chase levels in this game, Aku Aku is banned from this level, so even if the player has Aku Aku mask(s) when entering the level, the player loses the mask(s).
If the player repeatedly dies on a particular section of the level, then the boulder will slow down on that section of the level. This is a part of the Dynamic Difficulty Adjustment system that awards players an Aku Aku mask or an extra checkpoint on other levels, which wouldn't work in this level since Aku Aku is banned and checkpoints wouldn't make sense in the middle of a chase.
The third boulder sits higher on the platform than the others.
According to the Crash Bandicoot 2 Japanese October 1997 Trailer PlayStation Taikenban Vol. 2, this level was set on daytime instead of evening.
This is the second chase level in Crash Bandicoot 2, the first is Crash Dash and the third is Un-Bearable.
There is a secret area in this level's bonus round. It is located directly under the first platform after entering the bonus round. The area consists 21 additional wumpa fruit and an extra life. To access it, the player must fall to the left of the first platform.
The BradyGames strategy guide for this game lists the box total on this level as 48. The other differences between the guide and the actual game match those of the leaked beta version, in which this level has 57 crates, the same as in the final version. While it's possible that an earlier beta version was used to write the guide, it's more likely that the writers mistakenly inserted the box total for Bear It, the level immediately before Crash Crush.
