New 4PC Suggestion

Hi chess.com! I wanted to make a chess variant for today for 4PC (inspired by WoF games). This is the FEN4 for the game:R-0,0,0,1-0,0,0,0-0,0,0,0-0,0,0,0-0-{'royal':('h5','n8','g10','e7'),'lives':(5,5,5,5),'resigned':(null,true,null,null),'zombieType':('','patzer','',''),'zombieImmune':(false,true,false,false),'pawnsBaseRank':5}-
