Challenge mode is a gameplay mode featured in the entire Ratchet & Clank series, except the Series 40 version of Going Mobile, Quest for Booty, All 4 One, and Full Frontal Assault. After finishing the game, the player can replay it while retaining all weapons (including their upgrades and mods), their nanotech level, bolts, armor, skill points, and most collectible items and equipment. To compensate, enemies are more powerful and can withstand more damage. The player is granted a bolt multiplier, which increases in value based on how many enemies are destroyed without taking damage, up to a maximum of twenty.
Challenge mode is an option often presented to the player upon finishing the game, alongside the option to warp back to before defeating the final boss. This allows them to obtain any remaining secrets before proceeding. It is possible to have multiple challenge mode playthroughs, and in some cases, this is required to obtain all items.
Appearances[]
Ratchet & Clank (2002)[]
Challenge mode in the original Ratchet & Clank is available upon completion of the game.

In challenge mode, all ten gold weapons are available on Novalis or the Gemlik Base, as opposed to only five being available on the Gemlik Base in a normal playthrough.

The only items and gadgets that are retained in continued playthroughs are the Gadgetron PDA, Persuader, Bolt Grabber, and Map-o-Matic.
Though not called "challenge mode" in-game or in the original PlayStation 2 release, it is referred to as "challenge mode" on save files in the Ratchet & Clank Collection and standalone HD PlayStation 3 release.

Challenge mode in Going Commando is the first to be officially named "challenge mode" and the first to feature a bolt multiplier. After the credits and the final cutscene, a message appears, with the option to enter challenge mode by pressing or to time warp to before defeating the Mutant Protopet (though this is listed as "before defeating Captain Qwark") with . This version retains all bolts, platinum bolts, raritanium, weapons and their mods, nanotech level and nanotech boosts, armor, and ship upgrades from Slim Cognito's Ship Shack for the Star Explorer, as well as the Charge Boots, Mapper, Qwark statuette, Armor Magnetizer and Box Breaker.
New Mega Weapon upgrades become available for all upgraded weapons at a Megacorp vendor (excluding the Zodiac), including for Gadgetron weapons that normally cannot upgrade (excluding the RYNO II). Additionally, the new Clank Zapper becomes available. The Mega versions of Megacorp weapons can then be upgraded to an Ultra variant. These upgrades significantly increase the power and ammo capacity of weapons. The RYNO II can now also be bought everywhere (instead of just at Barlow). An armor vendor is now also available on Oozla. Normal nanotech crates restore four nanotech points each, while purple nanotech crates restore sixteen. Additionally, new gladiator challenges for the Megacorp Games and Galactic Gladiators open up. The maximum ammunition received from a pick-up is also doubled. Finally, some extras will be unlocked (or can be unlocked later) in the 'Special' menu.
The bolt multiplier follows a rounded equation, where Y is the multiplier and X is the number of enemies killed without being hit.
Up Your Arsenal[]
Challenge mode in Up Your Arsenal is available after the credits and final cutscene. A message appears, with the option to enter challenge mode by pressing , or to timewarp to before defeating the Biobliterator with

It also retains the Charge Boots, the Bolt Grabber V2, Gadgetron PDA, and the Nano-pak. The bolt multiplier is available, and is identical to Going Commando. Taking damage while driving a vehicle has no effect on the multiplier. Using a jackpot crate doubles the current multiplier, increasing it up to a maximum of 40.
Mega Weapons become available for all fully upgraded V5 weapons at a Gadgetron vendor, including for Megacorp weapons bought from Slim Cognito (which can then be upgraded to V8). The RY3NO becomes available in challenge mode for 3,000,000 bolts, and the bolt rewards for both Annihilation Nation and Galactic Rangers missions increase greatly. Maximum nanotech can also be upgraded to 200. Players can also skip Qwark-Vid comics to advance through the story more quickly, although no bolts or other rewards will be collected.
New bonuses will be unlocked in the 'Special' menu.
Deadlocked[]
Challenge mode in Deadlocked is available after the credits and final cutscene. A message appears, with the option to select "Yes" to enter challenge mode, while selecting "No" will time warp to before Gleeman Vox was defeated. All bolts, weapons (including the last Wrench Upgrade purchased), alpha mods, omega mods, and combat bot equipment and upgrades are retained. Mega versions of fully upgraded weapons can be purchased, allowing them to be upgraded to V99. The bolt multiplier is also available, up to a maximum of x20. Maximum nanotech can also be upgraded to 999.
Like prior games, extras (concept art, epilogue, etc.) are now available in the 'Extras' menu.
Going Mobile[]
In the Series 60 version, challenge mode is available after defeating Maximillion. The player retains all bolts, titanium bolts, weapons (with the exception of the Circuit Jammer), and their weapon progression. There are no further weapon upgrades beyond V3, and enemy damage and health appear unchanged.
Size Matters[]
Challenge mode in Size Matters is available after the credits. A message appears, with the option to press to enter challenge mode, or to go back to before defeating Otto Destruct. Like other games, a bolt multiplier is present, this time up to a maximum of x12. Titan versions of fully upgraded V4 weapons can be purchased from a Gadgetron vendor, allowing them to be upgraded to V8, while nanotech can be upgraded to 75.
The RYNO also becomes available for purchase at 9,999,000 bolts. More mods from Slim Cognito will also be available. The Hyperborean armor becomes obtainable throughout, while a third playthrough (second challenge mode playthrough) makes the Chameleon armor obtainable. The Giant Clank sections also become harder, with more enemies on screen, which in turn requires a higher score to obtain the skill points.
Items retained in this game are the PDA, Box Breaker, and Bolt Grabber.
Reaching a score multiplier of ×12, which requires 36 consecutive kills without being hit, in the PlayStation 4 and 5 versions unlocks the gold trophy Worker's Dozen.
Secret Agent Clank[]
Challenge mode in Secret Agent Clank is available after the credits. A message appears, with the option to press to enter challenge mode, or to go back to before defeating Klunk. Titan upgrades are available for Ratchet's fully upgraded V4 weapons, while Proto upgrades are available for Clank's fully upgraded weapons. The RYNO also becomes available for purchase for Ratchet, while Clank can acquire a new gadget, the Therm-Optic Shades, which allows him to scan alien codes. Three new weapon mods and the Hot Foot 2.1 Beta also become available for purchase. The price of ammunition is increased (up to three times as expensive), and the bolt multiplier is available (up to x12).
All items are retained upon entering challenge mode, including everything listed in the 'Special' menu.
Tools of Destruction[]
Challenge mode in Tools of Destruction is available after the credits. All bolts, raritanium, gold bolts, RYNO IV holo-plans, weapons at their current level with raritanium upgrades purchased, armor, and previously obtained devices are retained.
The Trillium armor can be bought at the armor vendor. Omega versions of fully upgraded weapons can be purchased, allowing them to be upgraded to version 10 (known as VX), and the Golden Groovitron becomes available for 2,000,000 raritanium. Prizes at the Imperial Fight Festival on Mukow, and the price for Leviathan souls sold to the Smuggler are multiplied by 100 (as before, Leviathan souls increase in value when sold on Sargasso).
The bolt multiplier is also available (up to x20). It is disabled in Clank and Aphelion sections. The bolt multiplier also increases raritanium dropped from pirate chests and enemies. The multiplier increase in this game is notably slow compared to previous games due to the differing requirements for defeating enemies. As a result, to maintain a high multiplier, the player should reserve the use of certain close-range weapons for situations such as running out of ammo for more powerful weaponry or finishing off lone, weak, or defenseless enemies.
The Decryptor puzzles in challenge mode are harder than in the first playthrough.
Items and gadgets retained are the Box Basher 2000, Armor Magnetizer, the Treasure Mapper, and Charge Boots.
A Crack in Time[]

Rift Apart[]
Once the player completes Rift Apart and the credits have finished, they are given the choice to either return to Zurkie's prior to the final battle or proceed to the title screen, where a new challenge mode playthrough can be started using the completed save file. Beginning challenge mode requires creating a separate save file.
