Warp Room

A Warp Room is an area in most early Crash games (Crash Bandicoot 2: Cortex Strikes Back to Crash Nitro Kart) from which a player can choose what level to play. The Warp Rooms in Crash Bandicoot 3: Warped and Crash Bandicoot: The Wrath of Cortex were very similar. Each Warp Room had sections that usually contained six entrances (five levels, sixth was usually the boss). Each world in each warp room have different themes. For example, in Crash Bandicoot 3: Warped, the first section of the Warp Room had a castle and fairytale theme) In Crash Bandicoot: The Wrath of Cortex the worlds were split into types of weather in different countries.

Crash Bandicoot 2: Cortex Strikes Back
This Warp Room is represented by six rooms connected via an elevator platform. The sixth room is secret and located underneath the first room. Each room has five levels. Once each level is complete, you may ascend to the next via the platform, but you must first fight a boss. Once the boss is defeated, the next room is accessible. To access the secret warp room, you must find certain secrets in levels that warp you to the secret room and unlock one of the levels there. This room has no platform that connects to the normal rooms. You can fight the bosses again by ascending from the bosses respective room and holding Triangle. Each room has its own theme:

Crash Bandicoot 3: Warped
This warp room is set in the Time Twister Machine and it has a different format that makes it quicker to switch between rooms. Each room is one the same screen (minus the secret sixth room, once again located under the default room) Each room has five levels and one boss (all located in the room) and once each level and the boss is complete, the next warp room will open. The sixth room can be accessed via a platform once five relics are earned.

Crash Bash
The Warp Rooms in Crash Bash act in the same way, except there is a different number of entrances in each room, the entrances lead to the games and you don't use lifts to get to the next.

Crash Bandicoot: The Wrath of Cortex
The Warp Room in this game, or Coco's VR Hub System is located on N. Sanity Island. It is a big laboratory built by Coco. There are five Warp Rooms on the first floor and a sixth on the second floor. Warp Room Six is accessed by a platform in the middle of the first floor after you clear the game.
 * 1) The first one is an earthy themed one. You can access all of Rok-Ko's levels.
 * 2) The second one is a water-themed one. It is raining in there and you can access all of Wa-Wa's levels.
 * 3) The third one is fiery. There is a huge fire in the background and you can access all of Py-Ro's Levels.
 * 4) The fourth one is an icy room. It is always snowing and you can access all of Lo-Lo's levels. It is weird that it is snowing. It would be more authentic if it was wind instead of snow.
 * 5) The fifth one is a green space-theme Warp Room. There is a picture of a galaxy in the background. This level has no elemental to defeat, just Crunch.
 * 6) The final one is a regular Warp Room. The player needs relics to access the levels. It is very secretly hidden but could be easily accessed accidentally if a player walks back towards the center.

Crash Twinsanity
In the demo version of Crash Twinsanity, the main room in the Iceberg Lab was used as a way to warp to each level. When approaching the warp entrance, Cortex would voice over explaining what the level was about, like a narrator.

Crash: Mind Over Mutant
When Crash needs to collect Uka Uka's stolen voodoo bones, he uses his powers to let Crash move around the island quickly. In the area where the Grimly is first met, three warp pads appear leading to Wumpa Island, the Wastelands, and Frozen Coast.
