Karnage Mode is the main mode of Kaiju Karnage. In it, up to four players can compete in online battles. Matches can be fought in different settings, including Stock and Time Limit. In Stock battles, each player has a preset number of lives; when a player's lives reach zero, they are eliminated. In Time Limit battles, the battle has a time limit; whoever is responsible for the most defeated opponents in the time limit wins. Players can fight a free-for-all battle or a 2v2 team battle.
