How to Play Last Breath Renewed Phase 2 Fight Simulator
In Last Breath Renewed Phase 2 Fight Simulator, you are thrust directly into the heart of the climactic second phase of the Last Breath AU. Unlike full trilogy ports that require playing through Phase 1 from the beginning, this standalone release focuses entirely on Phase 2's specific combat mechanics, high-speed bullet patterns, and narrative desperation. You take control of Frisk's SOUL at Level 19 with 92 maximum HP, facing a wounded Sans who refuses to let you reach the surface.
The core objective of Phase 2 revolves around a unique mechanical twist: your FIGHT button is shattered. At the start of the battle, Sans strikes the bottom interface, breaking the FIGHT command into scattered shards. Because you cannot strike back normally, your immediate goal is pure survival. You must endure consecutive attack turns, navigate defensive menus (ACT, ITEM, MERCY), and physically collect the seven floating FIGHT button pieces as they appear inside the arena across 17 intense attack waves.
Combat alternates between fast-paced dodging segments and menu navigation. During bullet waves, Sans shifts your SOUL between classic Red mode (free omnidirectional flight) and Blue mode (gravity-bound physics). Blue mode requires reacting instantly to telekinetic slams that hurtle your SOUL toward the ceiling, floor, or side walls, immediately followed by rising bone spikes. In addition, rotating Gaster Blasters fire high-intensity laser corridors across the box, demanding precision micro-movements to avoid taking devastating Karma damage.
Each turn in the 17-wave sequence introduces progressively tighter hazard configurations. Early waves challenge your basic vertical jumping rhythm over single and double bone hurdles. Mid-battle turns combine sweeping bone platforms with horizontal projectile volleys, forcing you to ride moving ledges while ducking under low-hanging obstacles. By Turn 12, Sans begins chaining multi-directional telekinetic throws in rapid succession, throwing your SOUL toward one wall only to immediately yank it toward the opposite boundary before you have even regained your footing.
Collecting all seven button fragments completely repairs the FIGHT button, unlocking your ability to deliver the decisive blow that concludes Phase 2. If you want to practice the final confrontation without enduring all preceding turns, this version includes a built-in practice shortcut: pressing the 0 key instantly transports you to Turn 17 right before the button is restored, allowing you to refine your endgame execution.
Controls and Input Mechanics
| Key | Action |
|---|---|
| Arrow Keys | Control SOUL movement during dodging phases (omni-directional in Red mode, jump and slide in Blue mode) and navigate menu buttons. |
| Up Arrow | Jump against active gravity in Blue SOUL mode. Tap lightly for short hops or hold down to achieve maximum jump height. |
| Z / Enter | Confirm menu selections, inspect combat prompts, advance dialogue, and trigger your strike once the FIGHT button is repaired. |
| X / Shift | Cancel current menu selections, back out of sub-menus, and quickly skip through repeating battle text. |
| 0 (Zero Key) | Developer and practice shortcut: jump directly to Turn 17 immediately before the broken FIGHT button is reassembled. |
Blue SOUL gravity responds dynamically to telekinetic slams. Always press the opposite direction immediately upon landing to avoid touching floor spikes.
About Last Breath Renewed Phase 2 and Version Details
Undertale: Last Breath is one of the most celebrated alternate universes in the Undertale fan community. Originally conceptualized with the premise of W.D. Gaster offering Sans a final chance to remember previous timelines and prevent the human's genocide run, the series became famous for its three distinct phases and demanding difficulty. Following the success of the original series, creator craKed_Wolf developed Undertale Last Breath Renewed, an overhauled reimagining that modernized the visual animations, redesigned attack choreography, and reworked the narrative pacing.
This standalone web edition, developed by Bad_Time_Trio1, specifically recreates the complete second phase of the Renewed vision. In this encounter, Sans appears with his jacket frayed, a bleeding red slash diagonally crossing his ribcage, and a pair of broken bone blades gripped tightly in his hands. Cyan and white energy crackles around his weapons as the battlefield echoes to the soundtrack "Close to Inevitability".
Understanding how this version compares to other Last Breath simulators is essential:
- Phase 2 Specialization: Unlike the standard Undertale Last Breath Simulator which hosts the full three-phase sequence with an integrated phase selector, this game is built exclusively around Phase 2. There are no Phase 1 blasters or Phase 3 giant hands; the entire engine is tuned for the broken-button survival gauntlet.
- Button Reassembly Mechanic: The hallmark feature of Phase 2 is the fragmented FIGHT command. Rather than dealing damage each round, you must dodge through 17 attack cycles while collecting 7 distinct button pieces floating through the bullet arena. Only after all seven pieces are collected does the button reform, permitting the final strike.
- Contrast with Community Parodies: This edition focuses on faithful recreation of craKed_Wolf's renewed choreography. It should not be confused with humorous community parodies such as Undertale Last Breath Phase 69 Fight Simulator, which replaces narrative progression with meme-inspired survival bullet hell.
- Menu Hazards and Blaster Engines: While you browse items or heal, floating bone walls patrol the edges of the selection buttons. Hovering too long or hesitating during menu selection risks taking incidental damage before the bullet wave even begins.
The visual presentation of Renewed Phase 2 sets it apart from earlier fan game iterations. Sans abandons his hands-in-pockets demeanor entirely, assuming an active combat stance with glowing bone daggers held in reverse grip. When performing bone attacks, his sprite physically lunges and sweeps his arms across the screen, visually syncing his gestures with the spawning of projectile walls. The dialogue box itself shivers under the strain of his telekinesis, reinforcing the high-stakes narrative tension.
The battle captures the exact feeling of fighting against an opponent on his literal last breath. By integrating responsive collision boxes, accurate Karma health drain, and fluid sprite animations, this simulator provides a dedicated training ground for one of the most mechanically demanding phases in the Undertale fan game pantheon.
Actionable Survival Tips and Strategy Guide
Conquering Last Breath Renewed Phase 2 requires exceptional reflexes and strict discipline. Keep these strategic guidelines in mind:
- Use Short Tap Hops: Tap the Up Arrow briefly rather than holding it down to avoid overshooting into ceiling bones during Blue SOUL phases.
- Patient Fragment Collection: Never risk high-damage hits to grab a button piece immediately; wait for clean gaps in the bone wave.
- Fast Menu Execution: Move through ACT and ITEM selections swiftly to avoid the bone barriers patrolling the lower interface.
- Purge Karma with Timely Heals: Eat healing items when your HP enters the yellow danger zone to halt purple Karma siphoning.
- Practice with the Zero Key: Press 0 to jump straight to Turn 17 and master the button-rebuilding climax.
- Dodge the Beam Indicators: Focus on the beam trajectory lines rather than the blaster sprites to dodge laser fire reliably.

Why is the FIGHT button broken at the beginning of the battle?
In Last Breath Renewed lore, Sans breaks the FIGHT button to prevent the human from attacking. To defeat him, you must survive through 17 attack waves while collecting seven button fragments that drift through the arena, eventually reforming the button.
Does this simulator include Phase 1 and Phase 3?
No. This game specifically focuses on Phase 2 as a standalone experience. If you want to play through the full multi-phase campaign with Phase 1 through Phase 3, you can play the comprehensive Undertale Last Breath Simulator.

Pressing 0 is a built-in shortcut that jumps directly to Turn 17, the moment immediately before the seventh button piece is collected and the FIGHT button is repaired. It serves as an excellent practice tool for mastering the final segment.
How does this compare to Undertale Last Breath Phase 69?
Last Breath Renewed Phase 2 is a faithful recreation of the serious narrative boss battle with authentic mechanics and button rebuilding. In contrast, Undertale Last Breath Phase 69 Fight Simulator is an arcade-style community parody focusing purely on extreme survival dodging.
What song plays during Phase 2?
The battle features the intense musical track 'Close to Inevitability' (a renowned Last Breath Phase 2 theme originally composed by Nick Nitro), capturing Sans's desperate struggle in the Last Corridor.
Can I play this simulator on desktop and mobile?
The game runs directly in modern desktop and mobile web browsers with standard keyboard controls. Because Phase 2 requires rapid arrow key precision, playing on a physical keyboard is strongly recommended for optimal dodging performance.
