In 4PC, there's a speacial move allowing u to eat (not checkmate) ur opp king. For example, in the game www.chess.com/variants/4-player-chess/game/49086655 my rook was on column k, then blue king didn't move out that column, then yellow move destroyed the protection of blue king. So I easily kill blue.
Not only king may be killed in that way, u can kill your far-moved opp by your last opp move. It's so interesting move, maybe for you!
