Crash Bandicoot: Warped is Naughty Dog's sequel to the previous game Crash Bandicoot 2: Cortex Strikes Back. Due to the events of the previous game, Uka uka (the twin brother of Aku aku) has been released from a sealed temple. It turns out that Uka uka was giving Cortex instructions the entire time! Soon after Uka uka is released, Aku aku tells Crash and Coco the story of him and his brother. Now freed once again, he must be stopped!
In this game, Crash uses the Time Twister Machine to go through time. To go into a level (or period of time) simply stand on a numbered button and jump in the portal ball in front of you.
The goal is to collect all 25 crystals, and defeating all 5 bosses. If you want to go even further, collect every Gem. Tip: the warp room has a gem too! Talk to Coco at the Load/Save Screen after you collect at least all the Gold Relics in every level.
Relics are obtained by completing a level fast. Each level has a Sapphire (slow), Gold (fast) and Platinum (very fast) time. The times vary between level and the region you live in (NTSC, PAL, and NTSC-J).
