Perfect for beginners and seasoned competitors alike, this resource will help you master one of the internet's most beloved fighting games.
Super Smash Flash 2 is a fan-developed crossover fighting game created by McLeodGaming, led by developer Gregory McLeod under the alias Cleod9. Built entirely in Adobe Flash with ActionScript 3, the game represents over 10 years of collaborative development by hundreds of contributors—a testament to Flash's underrated capabilities for game development.
The game serves as a spiritual successor to the original Super Smash Flash (2006), which was based on Super Smash Bros. Melee. Unlike its predecessor, Super Smash Flash 2 represents a complete reboot of the series, combining gameplay inspiration from multiple official Smash titles while adding its own creative innovations. The development team has described the game's design philosophy as "Frankenstein'd"—taking elements from Super Smash Bros. 4, Melee, and original mechanics to create a unique experience.
McLeodGaming's commitment to the project extends beyond Super Smash Flash 2; the team is actively developing Fraymakers, an original crossover fighting game. However, SSF2 remains their flagship title and continues to receive regular updates, with the latest version (1.3) released in February 2025.
Super Smash Flash 2 combines the familiar gameplay foundation of Super Smash Bros. with a diverse roster spanning video game, anime, and manga universes. The game's core appeal lies in three essential elements: accessibility, technical depth, and nostalgic character representation.
The game emphasizes a combo-driven fighting system with low landing lag, high hitstun, and high gravity—mechanics that create constant offensive opportunities and reward skilled play. Unlike some Smash games, combos are a fundamental part of SSF2's design, offering players meaningful ways to chain attacks and amplify damage through proper sequencing.
Instead of traditional health bars, Super Smash Flash 2 uses the percentage damage system found in official Super Smash Bros. games. Each hit increases an opponent's damage percentage, and the higher the percentage, the farther they'll be launched when struck. This creates dynamic risk-reward scenarios where early kills are difficult but become increasingly viable as the match progresses—a mechanic that rewards patience and proper spacing.
The game features globally reduced landing lag (often abbreviated as ALR—Aerial Lag Reduction), which varies from 3 to 12 frames at 30 FPS depending on the character. This design choice replaces L-cancelling from traditional Smash games, making the game more accessible to newcomers while maintaining technical depth for experienced players.
Version 1.3 (current as of February 2025) includes 47+ playable characters, representing the broadest crossover roster of any Smash fangame. The roster spans:
The game ensures that all characters have complete move sets with unique attacks, special moves, and final smash abilities, although some animations may undergo refinements before the full release.
Super Smash Flash 2 is available through multiple platforms, eliminating concerns about school or workplace blocking:

Browser versions have limited gamepad support due to inconsistencies across browsers. For serious players, the downloadable version is essential for controller play.
Unlike fighting games with health bars, Super Smash Flash 2 uses the percentage-based damage system:
This system creates natural match progression where early stocks are difficult to secure, but as percentages climb, a single hit can end the match. Strategic spacing and positioning become critical as opponents near KO percentages.
Super Smash Flash 2 features a diverse move arsenal:
| Move Type | Purpose | Speed |
|---|---|---|
| Jab | Quick combo starter, safe on shield | Very Fast |
| Tilts | Spatial control, combo utility | Fast |
| Smash Attacks | High damage, knockback, punishes | Medium |
| Aerials | Spacing tool, combo component | Medium |
| Specials | Character-unique abilities | Varies |
| Grab/Throw | Breaks shield, position advantage | Medium |

Classic Mode
Travel through a series of AI opponents of increasing difficulty. Complete the gauntlet to unlock rewards and new characters. Difficulty scaling makes this mode accessible to beginners while challenging advanced players.
All-Star Mode
Face every character in the game sequentially with limited health recovery between matches. This endurance mode tests your knowledge of multiple matchups and requires strategic character selection for optimal runs.
Events Mode
Participate in unique challenge scenarios with specific win conditions. Examples include defeating powerful opponents with handicaps, using limited item spawns, or achieving knockouts under unusual restrictions.
Training Mode
Practice against stationary or controlled opponents. Access frame-data overlays, record inputs, playback sequences, and test combos without time pressure. Essential for skill development and understanding character mechanics.

Spacing
Position attacks at maximum range (tip of attack hitbox) where opponents cannot punish. Safe spacing creates guaranteed advantages without counterplay.
Dash Dancing
Rapidly cancel dashes into opposing directions (toggle left-right quickly). Creates mind games, baits approaches, and resets neutral when disabled. Requires the Auto Dash option to be enabled.
Shield Pressure
Attack an opponent's shield with safe moves (aerials landing just outside their range). Forces them to react immediately or risk shield break.
Short Hop Attacks
Briefly tap jump, then immediately input aerial. Creates a lower attack arc, faster landing, and reduces oopponent'stime time.
Combo Starters
Ledge Trapping
Position near the stage edge when the opponent recovers from off-stage. Use aerials or tilts to prevent a safe landing. Force the opponent into a disadvantageous state.
Crouch Canceling
Crouch before an incoming hit to reduce knockback and hitstun. Cancel into grab, shield, or aerial to punish. Character-dependent; requires practice.
Perfect Shielding
Time shield activation frame-perfect as hits connect. Eliminates knockback and hitstun, enabling immediate punishment. Difficult but powerful in high-level play.
Directional Influence (DI)
Press direction inputs during hitstun to influence knockback trajectory. Proper DI can mean the difference between KO and survival at high percentages.
Center Stage Advantage
Maintain center position to control opponent movement. Corners restrict escape options; leverage this advantage.
Platform Usage
Jump to platforms to escape combos, reposition safely, or set up aerial-based approaches. Learn each stage's platform layout.
Off-Stage Advantage
Control space below and around the stage edge to prevent safe recoveries. Position aerials to force risky recovery options or punish common recovery patterns.
Habit Recognition
Identify patterns: Do they shield too much? Dash approach predictably? Roll in specific directions? Exploit detected habits.
Mix-Up Decision Making
Vary your approach options. If you always jab to combo, opponents will shield punish. Mix grab, shield, and dash options.
Punish Whiff
When the opponent misses an attack, they're vulnerable. Immediately capitalize with a grab, combo starter, or kill move before they recover frames.
Frame Advantage: Measure of time difference between attack recovery and opponent's ability to act.
Safe on shield attacks have small negative frames; unsafe moves risk grab punishment.
True Combos
Sequences opponent cannot escape if performed correctly. Marked in Training Mode combo counter.
Example Mario combo:
Combo Extensions
Non-true sequences requiring specific opponent positioning or percent ranges.
Example Isaac extension:
Dash Dancing Canceling (DDC)
Rapidly dash-cancel to bait opponent approaches while maintaining mobility advantage.
Shield Drop Fast Fall
Press shield + down simultaneously, then aerial attack for a quick approach from the shielding position.
Reverse Aerials
Face one direction while attacking the opposite direction. Creates spacing confusion and opens new combo opportunities.
Wave Dashing Alternative
Super Smash Flash 2 doesn't feature wave dashing. Instead, use dash-cancel-shield sequences for similar momentum control.
Positioning for Kill Confirms
Accumulate positioning advantages throughout the stock to set up guaranteed kill situations:
High-Percentage Conversions
At 90%+ damage, single hits often confirm kills. Spacing becomes critical; a single mistake resets neutral without a KO opportunity.
Ledge Snap Inconsistencies
Occasional missed ledge snaps during recovery on certain stages. Workaround: Angle recovery slightly differently.
Platform Clipping
Rare instances of characters passing through platforms. Typically resolved by moving the direction or shifting the stage position.
Animation Canceling
Some character animations cancel prematurely in early versions. Update to the latest version to resolve.
Flash Player End-of-Life (2020)
Adobe discontinued Flash support. Solutions:

Super Smash Flash (Original)
Fraymakers
Fighting Game Engines
To improve at fighting games generally:
Super Smash Flash 2 is a free browser-based fighting game featuring 47+ characters from video game, anime, and manga franchises. Developed by McLeodGaming, it combines Super Smash Bros. gameplay with a diverse character roster and technical depth accessible to both casual and competitive players.
Yes. Super Smash Flash 2 is entirely free to play with no premium content, battle passes, or pay-to-win mechanics. The development team explicitly refuses monetary compensation; supporting the game means continuing to play and enjoy it.
Super Smash Flash 2 is playable on Android devices (5.0+) through browser or app. iOS support is not available due to Apple's Flash restrictions and lack of native development for the platform.
No longer. While originally built in Flash, the downloadable desktop version runs independently. Browser versions use Ruffle (Flash emulator) or are hosted by partner sites with compatibility layers. Adobe Flash Player's 2020 discontinuation no longer affects gameplay.
Download the desktop version from supersmashflash.com, create an account (username, email, password, region), log in through the Online menu, then browse or create rooms in the multiplayer lobby. Internet connection required.
Yes—but only with the downloadable desktop version. Browser versions have limited controller support due to browser API inconsistencies. The desktop version supports Xbox, PlayStation, and generic USB controllers.
Mario, Kirby, and Link are ideal starter characters offering balanced movesets, accessible combo paths, and forgiving learning curves. Avoid high-skill-ceiling characters (Isaac, Ryu) until fundamentals are solid.
Practice fundamentals (spacing, shield pressure, combos) in Training Mode, play CPU matches at increasing difficulties, analyze replays to identify mistakes, learn character-specific techniques, and play online matches against human opponents for real decision-making pressure.
Absolutely. An active competitive scene exists with tournaments, ranked ladders (Anther's Ladder), and professional streamers. The game's technical depth, balanced roster, and online capabilities make it legitimate for competitive play.
The McLeodGaming team is currently focused on Fraymakers, an original fighting game, while continuing SSF2 updates. No announcement of a third Super Smash Flash game has been made.
Flash discontinuation (2020) caused compatibility issues. Unblocked gaming sites and official hosting now use the Ruffle emulator or compatibility layers. If issues persist, download the desktop version for reliable access.
Yes. Community tier lists exist, but change with updates. Current top tiers generally include Sonic, Pikachu, and Mario, but character viability is balanced enough that any character can achieve competitive results with proper play.
The game is not officially moddable. However, community members have created ROM hacks and custom versions. Use caution with unofficial versions regarding security.
No traditional story campaign exists. Classic Mode and All-Star Mode serve as single-player campaigns with escalating difficulty. Events Mode provides unique challenge scenarios.
