Fire Emblem X Kid Icarus

Fire Emblem X Kid Icarus is a crossover fighting game developed and published by Nintendo which features characters from Nintendo's video game franchises Fire Emblem and Kid Icarus.

Gameplay
Fire Emblem X Kid Icarus utilizes similar tag team-based game mechanics to its predecessor, Kid Icarus X Legend of Zelda. Before starting each match, the player selects a team of two fighters to compete in one-on-one combat. The player is free to swap between their characters at any point during battle. While one character fights, their teammate resting off-screen slowly regenerates their life gauge. The first team to exhaust their opponent's vitality wins the match; however, if the timer runs out before either team is knocked out, the player with the most remaining health is declared the winner
