SSF2 

SSF2 is the abbreviation for Super Smash Flash 2, the second "Super Smash Flash" game. On it's first release, it had few people, like Mario, Link, Kirby, Sonic, Ichigo, and Lloyd. During future developments, they had more adjustments, like adding in:

- Miles "Tails" Prower
- Black Mage (from "Final Fantasy")
- Bomberman
- Goku
- Chibi-Robo

...and others, making this the most played SSB-based flash game in the world.

SSF2 has a lot of cool stuff! Can't wait for its FINAL RELEASE!
