The following is the list of modes, as of present, in Super Animal World.
Royale

A SuperAnimal, alone or in a group, jumps out of a flying eagle and drifts (or hurtles) to the ground. As the skunk gas sweeps in, it must fight to be the last one standing.
This is very much Royale but with adjustments to core mechanics or available equipment. Each squad must fight to be the last one standing.
This is an inactive limited time mode and rarely comes into circulation.
Active Limited Time Modes

They want you! A SuperAnimal, alone or in a squad, works with other players and squads of one’s faction to beat back those on the enemy faction in a war of attrition.
Waking up in the middle of a zombie apocalypse is never fun, especially if you might already be infected – bwok! Survive until extraction, or claw and munch on all furvivors.
It is to be noted that while non-royale modes are also playable in teams of up to 4 players, since they are faction-based there is a lot less pressure to play in a group. Solo players can play in such modes just fine.
