What playing King of the Monsters is like

Fighting games pit two characters against each other in short one-on-one bouts. Depth comes from learning special moves, combos and each character's strengths.

Tip for newcomers: Pick one character and learn their basic special moves before branching out. Fighting games are at their best against a friend at a similar skill level.
