How to Play Burgerpants Fight Simulator
Unlike the official Undertale game where Burgerpants is simply a shopkeeper you interact with through a static menu, this simulator places him directly into a dynamic battle encounter. The gameplay loop is divided into two main phases: the overworld exploration and the actual combat.
When you first load the game, you will find yourself in the overworld section. Here, you use your controls to interact with Burgerpants and progress the dialogue. This section is crucial because the choices you make and the way you interact with him before the battle officially starts can influence the narrative trajectory. To begin the actual combat, you must advance through these initial text screens. Take your time to read the dialogue, as it provides context for why the fight is happening and sets the emotional stakes for the encounter.
Once the battle initiates, the interface shifts to the familiar Undertale battle system. You will control a red soul inside a restricted bullet board. Your primary goal is to survive Burgerpants' unique attacks by dodging incoming projectiles. During your turn, you will have the standard options to Fight, Act, use Items, or attempt to Spare him. Managing your health is critical, as his attacks can be surprisingly punishing. You must decide whether you want to aggressively attack him to end the fight quickly or use the Act menu to understand his emotional state and work towards a peaceful resolution.
The controls in the Burgerpants battle simulator rely on the standard Undertale mechanics but introduce specific ways to interact with both the dialogue and the combat menus. Mastering these controls is essential for navigating the complex attack patterns and achieving your desired ending.
Burgerpants Fight Controls
| Key | Action |
|---|---|
| Arrow Keys | These are your primary movement controls. During the battle phase, use the Up, Down, Left, and Right arrow keys to move your red soul and dodge attacks. In the overworld and battle menus, use them to browse between different interactive options. |
| Z or Enter Key | This serves as your primary action button. Use it to select an option in the menu, confirm an action, or advance the dialogue text in the overworld. When Burgerpants is speaking, pressing Z will move to the next line of dialogue. |
| X Key | The X key has dual functionality depending on the current phase of the game. In the overworld or during dialogue sequences, pressing X allows you to skip the text quickly, which is useful for subsequent playthroughs when you already know the story. During the battle phase, holding down the X key will slow down the movement speed of your red soul. This precision mode is vital for dodging tightly packed bullet patterns. |
About the Burgerpants Battle
Step into the Burgerpants Fight Simulator, a unique fan-made Undertale battle created by LucasBr003. Burgerpants is famously known as the highly stressed, overworked 19-year-old employee trapped working at the MTT Resort burger emporium. While the official Undertale game only features him as an entertaining shopkeeper NPC who shares his grievances about his boss, Mettaton, this simulator asks the question: what if Burgerpants finally snapped and you had to face him in a genuine boss encounter? This game places you directly into that hypothetical scenario, allowing you to navigate through custom dialogue, survive unique attack patterns, and discover multiple story endings.
The Burgerpants Fight Simulator stands out among other fan-made Undertale battles because it does not simply throw you into an immediate bullet hell. Instead, it carefully crafts a narrative experience that feels authentic to the original game's tone. You will start in an overworld setting where you can interact with the environment and characters. The creator has included custom sprites by Askywalker and utilized a carefully selected soundtrack, including original pieces, to make the encounter feel like a natural extension of the Undertale universe. Whether you are looking for a challenging fight or just want to experience a new interactive story involving everyone's favorite stressed cashier, this simulator provides a comprehensive and engaging experience.
The concept of a Burgerpants boss fight is entirely original to the Undertale fan community. In the canon game created by Toby Fox, Burgerpants serves purely as a comedic relief character and a vendor who sells healing items like the Glamburger and Starfait. His dialogue mostly revolves around his miserable job, his unrequited feelings for Catty and Bratty, and his fear of Mettaton.
This simulator takes those established character traits and weaponizes them. The creator, LucasBr003, along with sprite artist Askywalker, has designed a fight that reflects Burgerpants' chaotic mental state. The attacks aren't just random geometric shapes; they are thematic representations of his stress, his job at the fast-food restaurant, and his overall anxiety. This thematic consistency elevates the simulator from a mere mechanical challenge to a piece of interactive fan fiction.
Furthermore, the game incorporates a custom soundtrack that blends official Undertale tracks with original compositions. You will hear familiar tunes like "Quiet Water" and "Can You Really Call This A Hotel I Didn't Receive A Mint On My Pillow," alongside custom tracks like "I Always Get the Freaks" composed specifically for this encounter. This auditory landscape helps to immerse you in the setting of the MTT Resort and the specific emotional tone of the battle.
Burgerpants Battle Mechanics and Attack Types
The fight simulator features several distinct attack colors and mechanics that you must respond to correctly. Failing to understand the specific rules of each attack type will result in taking rapid, unavoidable damage.
First and foremost are the White Attacks. These are the standard projectiles you encounter in most Undertale battles. They have no special properties other than causing damage upon contact. Your only strategy here is to move your soul out of their path to dodge for your life.
Next are the Blue Attacks. When these light blue projectiles or beams appear on the screen, the rule is simple: make sure your soul is completely STOPPED. If your soul is stationary when a Blue attack passes over it, you will not take any damage. Even the slightest movement will cause the attack to register a hit. You must anticipate when these are coming and release the arrow keys immediately.
Conversely, the game features Orange Attacks. These function as the exact opposite of Blue attacks. When an Orange projectile approaches, you must be continuously moving through it to avoid getting hurt. Standing still while an Orange attack passes over your soul will result in damage. This forces you to stay active and prevents you from simply hiding in a corner.
Burgerpants will frequently mix these colors within a single attack wave. You might have to dodge a White projectile, stop for a Blue wave, and immediately start moving again to pass through an Orange barrier. This requires quick reflexes and strong pattern recognition.
Tips for the Burgerpants Battle
- Hold X for Precision Dodging: The ability to slow down your soul by holding the X key is arguably the most important mechanic in the game. When the screen fills with projectiles, moving at full speed can cause you to accidentally run into attacks. Use the slow movement to squeeze through tight gaps and navigate complex mazes safely.
- Anticipate Color Changes: Because Burgerpants mixes Blue and Orange attacks, you must constantly be mentally prepared to either halt all movement or sprint forward. Watch the edges of the bullet board to see which colors are spawning next and plan your movement accordingly.
- Don't Skip Dialogue on Your First Run: If it is your first time playing, carefully read the text using the Z key instead of skipping with X. The dialogue contains subtle hints about his emotional state, the context of the story, and clues on how to achieve specific endings.
- Explore the Multiple Endings: The simulator features a branching narrative with multiple conclusions. Pay attention to the text colors during the ending sequences. Purple text indicates the main endings, Yellow indicates secondary endings, and Gray points to highly elusive secret endings. Try different combinations of fighting, acting, and sparing to uncover them all.
- Prioritize Evasion Over Rushing: His attacks can deal significant damage very quickly. It is always better to focus entirely on dodging rather than trying to rush through your turn. Take your time, learn the patterns, and strike only when you are confident you can survive the next wave.
- Pay Attention to the Act Menu: The Act menu isn't just for show. Interacting with Burgerpants in specific ways can alter his dialogue, change the flow of the battle, and open up pathways to the non-violent endings. Experiment with all available options.
Frequently Asked Questions
Is Burgerpants a real boss in Undertale?
No, in the official Undertale game, Burgerpants is strictly an NPC. He is a shopkeeper located at the MTT Resort who sells healing items and provides humorous commentary about his life. This battle is a fan-made concept that imagines what fighting him would mechanically and narratively entail.
Can I play the Burgerpants Fight Simulator on a mobile device?
While the game relies primarily on keyboard controls (specifically the Arrow keys, Z, and X), mobile compatibility largely depends on your mobile browser's ability to emulate these specific keyboard inputs. For the intended and optimal experience, playing on a desktop or laptop with a physical keyboard is highly recommended.
How do I unlock the secret gray endings?
The secret endings, which are denoted by gray indicators at the conclusion of the game, are unlocked by performing specific, non-obvious combinations of actions during the fight. This usually involves choosing a very specific sequence of options in the Act menu rather than relying on standard attacks or a simple mercy route.
Why do I keep taking damage when I am standing perfectly still?
If you are taking damage while your soul is stationary, you are almost certainly being hit by an Orange attack. The fundamental rule of Orange attacks is that you must be actively moving to pass through them safely. Standing still guarantees a hit.
What exactly does the X key do during the combat phase?
During the actual battle phase (when you are controlling the red soul inside the box), holding down the X key slows down your movement speed. This "focus mode" gives you significantly more precision, making it much easier to dodge dense or complex attack patterns without accidentally oversteering into a projectile.
Who is responsible for creating this Burgerpants battle?
This specific fan-made Burgerpants Fight Simulator was coded and developed by the Scratch user LucasBr003. The custom Burgerpants character sprites used in the battle were created by another user named Askywalker.
Are there different phases to the fight like in the official game?
Yes, the flow of the battle changes depending on how you interact with him and how much damage you deal. The dialogue and the intensity of the attacks will shift as the encounter progresses, mirroring the multi-phase structure seen in many official Undertale boss fights.
