About Super Smash Flash 2

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.

Game Overview & Features

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.

Core Gameplay Philosophy

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.

Character Roster

Version 1.3 (current as of February 2025) includes 47+ playable characters, representing the broadest crossover roster of any Smash fangame. The roster spans:

• Nintendo Franchises: Mario, Luigi, Peach, Bowser, Yoshi, Wario, Waluigi, Donkey Kong, Diddy Kong, Link, Zelda, Ganondorf, Pikachu, Jigglypuff, Pichu, Captain Falcon, Samus, Zero Suit Samus, Kirby, Meta Knight, Marth, Mr. Game & Watch, Ice Climber, Falco, Fox, Krystal
• Sega/Third-Party: Sonic, Tails, Mega Man, Pac-Man, Ryu, Simon
• Anime/Manga Characters: Naruto, Ichigo (Bleach), Goku, Vegeta, Lloyd (Tales of Symphonia), Sora (Kingdom Hearts), Black Mage (Final Fantasy), Rayman
• Unique Additions: Isaac (Golden Sun), Sandbag, Bandana Dee, Chibi-Robo, Robo, Lucario

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.

Gameplay Mechanics & Core Systems

Damage & Knockback System

Unlike fighting games with health bars, Super Smash Flash 2 uses the percentage-based damage system:

• Starting Percentage: All characters begin matches at 0%
• Damage Accumulation: Each hit increases the damage percentage
• Knockback Scaling: Higher percentages equal greater knockback distances
• KO Threshold: Knock an opponent off the stage to achieve a knockout

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.

Damage Reduction Mechanics

• Shielding: Hold Shield (I key) to block damage and reduce knockback (shield takes damage over time)
• Perfect Shield: Time your shield activation precisely as attacks land to negate knockback entirely
• Crouch Canceling: Crouch to reduce knockback from incoming attacks; can chain into grabs or aerials
• Directional Influence (DI): Input directions during knockback to influence your trajectory

Attack Types & Speed

Super Smash Flash 2 features a diverse move arsenal:

Hitstun & Landing Lag

• Hitstun: Frames opponent is locked in hitlag animation; enables combos
• Landing Lag: Frames of vulnerability when landing from aerials
• Global Landing Lag Reduction (ALR): 3-12 frame reduction depending on character, allowing safer aerial approaches

Tips & Tricks for Success

Neutral Game Fundamentals

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.

Offensive Techniques

Short Hop Attacks
Briefly tap jump, then immediately input aerial. Creates a lower attack arc, faster landing, and reduces oopponent’stime time.

Combo Starters

• Jab Reset: Quick hit that sends opponent slightly into the air, enabling grab or aerial follow-up
• Down Throw: Position-specific throw enabling different combos
• Dash Attack: Fast approach combining movement and attack

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.

Defensive Strategies

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.

Stage Control & Positioning

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.

Reading Opponents

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.

Practice Methodology

1. Training Mode: Execute combos, test kill thresholds, learn frame data
2. CPU Battles: Practice a neutral game against varying difficulties
3. Replay Analysis: Review losses to identify mistakes
4. Character Labs: Dedicate sessions to learning one character thoroughly
5. Online Ladder: Play ranked matches to test improvement

Advanced Techniques & Combos

Frame Data Fundamentals

Frame Advantage: Measure of time difference between attack recovery and opponent’s ability to act.

• Positive Frame Advantage: You act first, enabling follow-ups
• Negative Frame Advantage: Opponent acts first; vulnerable to punishment
• Frame Neutral: Both can act simultaneously; neutral reset

Safe on shield attacks have small negative frames; unsafe moves risk grab punishment.

Combo Theory

True Combos
Sequences opponent cannot escape if performed correctly. Marked in Training Mode combo counter.

Example Mario combo:

• Down Throw → Up Air → Up Air (true at 0-30%)
• Jab → Jab → Up Tilt → Short Hop Up Air (true at 0-40%)

Combo Extensions
Non-true sequences requiring specific opponent positioning or percent ranges.

Example Isaac extension:

• Dash Grab → Down Throw → Dash → Up Smash (works 20-80%)

Advanced Movement

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.

Kill Setup Sequencing

Positioning for Kill Confirms
Accumulate positioning advantages throughout the stock to set up guaranteed kill situations:

1. Control center stage
2. Drive opponent to the ledge through spacing
3. Mix approaches forcing predictable reactions
4. Punish recovery for the final stock

High-Percentage Conversions
At 90%+ damage, single hits often confirm kills. Spacing becomes critical; a single mistake resets neutral without a KO opportunity.

Glitches, Exploits & Known Issues

Documented Glitches (Pre-1.3 Versions)

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.

Browser Compatibility Issues

Flash Player End-of-Life (2020)
Adobe discontinued Flash support. Solutions:

• Use Ruffle Emulator (browser extension)
• Download desktop application (recommended)
• Access through browser versions on unblocked gaming sites (Classroom 6x, KBHGames)

Performance Drops
If experiencing lag:

1. Close other browser tabs/applications
2. Switch to the downloadable version
3. Reduce background processes
4. Try a different browser (Chrome recommended)
