Returning in Sengoku Basara 3 Utage is a revamped Tag mode. Unlike the Tag mode in Sengoku Basara 2 Heroes, this Tag Mode is NOT limited to Arena/Mission modes and can be used in nearly every mode.
To unlock Tag Mode, you must unlock every character. This can be done by clearing the 8 Sengoku Basara 3 Utage story modes.After clearing the last story mode, you should receive an extra message indicating tag mode is unlocked.
Only playable characters can be used for tagging.
The tag feature allows you to switch between your main character and your ally. Your ally will not remotely assist you like usual. To be able to use an ally for tagging, the ally must have his ally level MAXED at level 5. This can be done by clearing 5 stages with the ally equipped or by beating a mission in Japan's event mode that awards that ally while the ally is already unlocked.
When you select a maxed ally, you will be presented with the screen depicted above. Select the TAG option on the right.
To Tag in battle, hold L1 and Press X.
'Experience points gained in Tag mode are divided between both characters just like in co-op. 'Tag mode CANNOT be used whe playing with a second player.
