Mortal Kombat is famous for Fatalities—cinematic, gory endings. But once you’ve seen a Fatality 100 times, you skip it. They break the flow.
Killer Instinct offers the Ultra Combo. After winning a round, the announcer screams "ULTRAAAA!" and you manually control your character for 15 seconds, juggling the opponent across the screen.

MUGEN is a free, 2D fighting game engine developed by Elecbyte. Think of it as the ultimate "fighting game Lego set." You can take any character from any franchise—from Street Fighter to Dragon Ball, from obscure anime to original creations—and pit them against each other.
For years, the MUGEN library was flooded with weak, unbalanced "chibi" characters or broken joke fighters. However, a dedicated sect of creators has been quietly building something incredible: HD, arcade-perfect ports of Killer Instinct characters.
