CO-OPS Actions
CO-OP Ring

During CO-OPS, a ring is displayed around each character. If at a distance where both rings are touching, a larger ring will appear around everyone. Entering this larger ring is called "CO-OP IN" and leaving it is called "CO-OP OUT."
The Merits of CO-OP IN
while viewing the Weapon/Equipment Window to view the items of your allies.
Snake Formation

During CO-OPS, if you hold the Action Button continuously near a comrade, you will enter Snake Formation, which allows you to move as a group in a column. This is called "Snake In" and leaving the formation by letting go of the Action Button is called "Snake Out."
While in Snake Formation, the player in front controls movement of the group. Because the other players will follow automatically, they can devote their time to looking out for enemies and attacks. Players are also able to climb heights in Snake Formation that are otherwise inaccessible.
- Go to "Snake Formation" in the OPTIONS menu to enable toggling in and out of the formation using the Action Button.
Snake Sync
When in Snake Sync Mode, your movements and recovery will be faster and your Camo Index will increase, with the effects influenced by your Camaraderie level.

CPR
During CO-OPS, a player will not die even if their LIFE Gauge reaches zero and enter a near-death state instead. While players are unable to move in this state, if another players approaches them, they can perform CPR and revive their comrade.
However, performing CPR during battle is dangerous and can put one's own life at risk.
- If all player's LIFE Gauges are reduced to zero, the game is over.

Love Box
Up to two people can enter the Love Box. Press the Action Button near a box containing a comrade to enter. It is also possible to enter the Love Box as a pair while in Snake In Mode.
