100% Completion

100% Completion is the act of collecting everything in a video game. In most of the Crash Bandicoot games, players can go over the 100% mark. Sometimes, there's even rewards for getting 100%. In almost all the Crash games, getting 100% is required for the true ending.

Crash Bandicoot
In this game, the highest percentage is 100%. To get 100%, the player must beat every level and boss, collect all the gems, and collect both keys. Although it is possible to access Stormy Ascent through hacking, neither clearing the level nor obtaining its Clear Gem increases the gem screen's percentage.

The percentage is rounded down to the nearest integer. For example, with 15 levels, 7 gems and 1 key, the value is 38/88≈43.18%, which rounds down to 43%. Also, each key is worth 1/88 on its own, but since it also unlocks one level, its total value is 3/88. It's impossible to get a total of 8%, 16%, 24%, 33%, 41%, 49%, 58%, 66%, 74%, 83%, 91%, or 99%.

Among all 33 levels (including bosses), N. Sanity Beach is available from the start, while The Great Hall and Dr. Cortex count as the 32 unlockable levels but don't count towards the percentage, leaving 30 levels to count towards percentage.

Crash Bandicoot 2: Cortex Strikes Back
In this game, the highest percentage is 100%. To get 100%, the player must collect all 25 crystals and collect all 42 gems. Additionally, even though it is possible to get the red gem from Snow Go and the box gem from Road to Ruin without going through the secret warp room, each of the five warps to the secret warp room also adds 1% to the player's completion percentage, so the player must access all of those warps to the secret warp room to get 100%. However, the player can view the 100% ending by simply having all crystals and all gems and defeating Dr. Neo Cortex, without necessarily having 100%.

* It is possible to get up to 200% with 64 crystals and 64 gems via a glitch.

Crash Bandicoot 3: Warped
In this game, the highest percentage is 105%*. To get 105%, the player must collect all Crystals, collect all gems, and collect gold or platinum relics on every level. By collecting all crystals, gems, and relics (of any type) on the main levels (i.e. excluding Hot Coco and Eggipus Rex), the player gets 100% and the second ending can be viewed and the platinum relic times appear. Hot Coco and Eggipus Rex are considered bonus levels, and the player gets the extra 5% by doing the following:

* Like in Crash 2, it is possible to get much higher percentages through the same glitch.
 * 1% for Hot Coco gem
 * 1% for Hot Coco relic
 * 1% for Eggipus Rex gem
 * 1% for Eggipus Rex relic
 * 1% for the 45th gem acquired when the player has obtained all of the other gems and a gold or platinum relic on every level (including Hot Coco and Eggipus Rex)

Crash Team Racing
In this game, the highest percentage is 101%. To get 101%, the player must collect all trophies, CTR tokens, gems, and have a gold or platinum relic on every track. The player can view another ending, each of the character's epilogue can be seen, and they will have confetti.

Crash Bash
In this game, the highest percentage is 200% when playing a one player game, or a two player game in which both characters chosen are on the same team. To get 200%, the player must collect all trophies, gems, crystals, and all gold and platinum relics.

When playing a two player game with one good character and one evil character, 200% is achieved in the same way, and then there is a tie breaker. After playing the tie breaker, the percentage rises to 201%. However, this only works in the NTSC version of the game. The percantage doesn't rise to 201% in the PAL version, instead it stays on 200% even after Tie Breaker.

Crash Bandicoot: The Wrath of Cortex
In this game, the highest percentage is 106%. To achieve this percentage, the player must collect all crystals, gems, and relics. Any type of relic will suffice as no extra percentage is given for gold or platinum relics. After obtaining 106% completion, the player can view the game's second ending by completing the Crunch Time boss fight again.

This game contains 25 crystals, 46 gems, 30 relics, and 5 boss fights. Each of these accounts for 1%, and so the fact that these add up to 106 is the reason why total completion in this game is 106% instead of 100%.

Crash Bandicoot: The Huge Adventure
In this game, the highest percentage is 101%. 100% is achieved by collecting all crystals, gems, and relics from the 20 main levels. If the player additionally gets a gold or platinum relic on every level, and defeats Cortex again, the Mega-Mix level will be playable as part of the game's second ending. Acquiring the gem from this level will bring the percentage to 101%.

Crash Bandicoot 2: N-Tranced
To reach 100% completion, the player must collect all crystals, gem shards, gems, and at least 16 platinum and 8 gold relics and also defeat N. Tropy.

Crash Nitro Kart
To reach 100% completion, the player must have all trophies, CNK Tokens, gems, relics, and keys, and must then beat Velo again to unlock the 100% cutscene (which varies between teams).

Crash Twinsanity
100% completion is reached by collecting all the crystals and gems and defeating all the bosses. A special cutscene is unlocked in the extras menu (which varies between regions).

Crash Tag Team Racing
To get the maximum percentage, 100%, the player must beat all Chicken Challenges, get all crystals, find all Die-O-Ramas, unlock all gags, and unlock all vehicles and vehicle upgrades. There is no extra reward for reaching 100% completion.

Crash Bandicoot N. Sane Trilogy
It is possible to complete the remake of the first Crash Bandicoot game 102% by completing all levels as well as getting all the gems, keys, and the additional ending by stepping on the gems in The Great Hall; with gold or platinum relics contributing the final 2%. The game can be completed to a maximum of 105% by completing the downloadable level Stormy Ascent and getting its associated gem.

Similarly, the remake of Crash Bandicoot 2: Cortex Strikes Back also has a maximum of 102% completion, again with gold or platinum relics contributing the final 2%.

Like the original, the remake of Crash Bandicoot 3: Warped still has 105% completion, and is achieved in the same way. However, the percentage can be increased to 108% by getting the Gems and Relic from the downloadable level Future Tense. * Every relic must be obtained to gain an extra 1% on a save file for the first two games. Another 1% can be added by having every relic at gold or platinum status.

** Due to a glitch, 105% can only be reached if Whole Hog, Fumbling in the Dark and Stormy Ascent are completed (with gems) before finishing the final boss level. If Cortex is defeated first, the counter will never go past 104%, and the only way to gain the extra 1% is to start a new game.
