New Game+ and Lethal Mode

This is the page to read after the endgame escape, when you are deciding whether to keep pushing New Game+ or start Lethal Mode.

Quick Answer

Question	Answer
How do you enter New Game+?	Finish the regular endgame escape. The game creates a fresh regular save with the New Game+ counter increased by 1.
Does New Game+ cost anything?	NEW GAME+ UPGRADES says New Game+ itself is free. The new post-clear spend is the NG+ Shop in Darts.
Where is the NG+ Shop?	The NG+ Shop is in the Darts room.
What carries over?	The save tracks the New Game+ count and completed-game state. Tutorial counters are pre-marked so the next loop does not behave like a first boot.
What gets harder?	Normal upgrade growth becomes steeper, and every bodyguard bribe jumps by a power of ten for each New Game+ layer.
Does the room order change?	Darts -> Lotto -> Pachi -> Sushi -> Gacha -> Endgame stays the core route.
Is Lethal Mode the same save?	No. Lethal Mode is launched separately and uses its own save path.
Can Lethal wipe regular progress?	No. Lethal start, Lethal completion, and Lethal game-over use the separate Lethal save path, not the regular save.

New Game+ Bribe Costs

Bodyguard bribes are the clearest New Game+ wall. They do not use the normal shop discount path. The formula is one million times ten for each New Game+ layer.

Layer	Bodyguard Bribe Cost	What It Means
First run / NG+0	1,000,000	The normal first-clear bodyguard price.
NG+1	10,000,000	Each bodyguard costs ten times the first-run price.
NG+2	100,000,000	Unlocking the next room becomes a serious currency check.
NG+3	1,000,000,000	You need stronger cross-room scaling before paying bribes casually.
NG+4	10,000,000,000	Bribes become one of the main reasons to optimize the loop.
NG+5	100,000,000,000	Expect room unlocks to require planned multiplier stacking.

The same pattern applies to each bodyguard in the route: Verminious for Lotto, Gorgon for Pachi, Rimmington for Sushi, Hivemind for Gacha, and Executor for Endgame.

Upgrade Cost Scaling

Normal upgrades still use their base cost and growth rate, but New Game+ makes the growth above 1.0 larger. The player-facing formula is:

Base 1.0 plus the upgrade’s extra growth multiplied by (1 + 0.25 x New Game+ layer).

Original Growth	NG+0	NG+1	NG+2	NG+3
1.25x	1.25x	1.3125x	1.375x	1.4375x
2.00x	2.00x	2.25x	2.50x	2.75x
10.00x	10.00x	12.25x	14.50x	16.75x

This matters most for upgrades with high growth or many levels. A cheap upgrade can still become expensive quickly if you push it deep in later New Game+ loops.

NG+ Shop In Darts

NEW GAME+ UPGRADES added 40 upgrades that are exclusive to New Game+. The shop for those upgrades is in Darts, so the first room is no longer just an early-loop currency ramp after you have cleared the game.

New Game+ itself is free. The new spending decisions are inside the Darts-room NG+ Shop, and the announced examples are broad enough that Darts now matters for the whole loop: +10 total darts thrown, 125x Platinum, +1000% Dart Throwing Speed, +1000% Accountant Toad Speed, 50x Bubba Ball Launch speed, and 125x Abacus Frog EXP in Lotto.

NG+ Shop Range	Unlock Condition	Why It Matters
Upgrades 1-20	Available from the NG+ Shop path before the later clear gates named in the patch notes.	Builds the first layer of NG+ speed and cross-room scaling.
Upgrades 21-30	Unlock after beating New Game+.	Rewards the next full clear with another block of NG+ upgrades.
Upgrades 31-40	Unlock after clearing the second New Game+ layer (`NG++`).	Turns repeated clears into continued shop progression instead of only higher bribe and cost pressure.

What To Prioritize In New Game+

Check the NG+ Shop in Darts early in each post-clear loop. The June 6 patch made Darts the hub for New Game+-exclusive upgrades.
Unlock rooms sooner instead of over-leveling every early-room upgrade. Later rooms add systems that make earlier currencies easier to scale.
Treat bodyguard bribes as planned goals. Coupons help normal shop upgrades, but the bodyguard bribes ignore normal cost reduction.
Buy automation and helper unlocks early when they prevent manual bottlenecks: Auto Throw, Rattling Gunner, Accountant Toad, Bubba, Ghost Janitor, Poppy, and Trash Goose.
Prioritize cross-room scaling once several rooms are open. Sushi bonuses, Gacha items, helper effects, Shadow Realm, and Trial Mode do more than isolated single-room upgrades.
Before paying the next bribe, check whether a cheaper multiplier in another room would make the bribe faster.

Lethal Mode

Lethal Mode is not just a modifier on your regular save. It is launched separately from the main menu, creates a Lethal save if one does not exist, and resets through its own completion or game-over path.

Mode	Starts From	Save Behavior	Use It For
Regular New Game+	Regular endgame completion	Replaces the regular save with a fresh New Game+ setup and increments the NG+ count.	Continuing the main progression loop.
Lethal Mode	Main-menu Lethal option	Uses a separate Lethal save. Completion and game over reset that Lethal save separately.	A separate challenge route that should not be treated as normal NG+.

What Carries Over

Mode	What Happens
Regular completion	The main save is replaced with a fresh New Game+ setup. The NG+ count increases by 1 and tutorial counters are pre-marked.
Lethal start	If no Lethal save exists, the game creates a separate Lethal save with Lethal Mode marked true.
Lethal completion	The Lethal save resets through the Lethal completion path.
Lethal game over	The Lethal save resets separately; it does not wipe the regular save.

See Save Data and Carryover for the full saved-state list. The important practical point is that New Game+ feels like a fresh loop with a higher layer counter, not a continuation where every ordinary upgrade and currency total simply stays intact.

FAQ

Question	Answer
Why did the next bodyguard become so expensive?	Bodyguard bribes use one million times ten to the New Game+ layer. NG+1 is 10,000,000, NG+2 is 100,000,000, and so on.
Why does Darts matter again after the first clear?	The NG+ Shop is in Darts, and the June 6 patch’s example upgrades include total darts thrown, Platinum gain, Dart Throwing Speed, helper speed, Bubba ball speed, and Abacus EXP.
Do coupons reduce bodyguard bribes?	No. Room coupons reduce normal shop costs, but the bodyguard bribes and main coupon upgrades ignore that reduction path.
Should I max a room before unlocking the next one?	Usually no. Unlocking the next room gives new systems, helpers, and cross-room effects that often beat grinding every local upgrade first.
Is Lethal Mode just New Game+ with harder numbers?	No. Lethal Mode is separate from the regular save path and should be treated as its own challenge route.
Where should I go next?	Use Room Unlock Order for the route, Upgrade Costs for scaling, and Troubleshooting if the loop appears stuck.
