CyberConnect2 describes Survival Mode as a situation where you the player fight multiple computers opponents, one at a time. Health does recover, but only if the opponent is defeated quick enough and/or skillfully enough. That means you (the player) need to avoid taking damages, keep defeating opponents and survive until the end!
YouTube user trander96 has kindly sent Anime Games Online videos to describe the Naruto Generations survival mode in detail! Survival Mode is split into a few different levels (these names are subject to change when the game comes out in North America and Europe) – Introductory Stage Survivor, Beginning Survivor, Intermediate Survivor, Advanced Survivor, and Expert Survivor.
The first 20 seconds in the the video below shows Introductory Stage Survivor. As the name implies, it is the easiest, and gets players started by fighting 2 or 3 characters in a row. Then the competition get a little tougher in Beginning Survivor as players have to battle 2 to 7 characters in a row. 42 seconds in is the next level up, Intermediate Survivor, which has 4 to 11 characters that must be fought in a row.
The first battle in Advanced Survivor is also shown, as it has players taking on five characters in a row. While we can’t say for sure, we do imagine Advanced Survivor and Expert Survivor will have even more characters to fight with in addition to higher difficulty levels. As with all the levels in Survival Mode, in order to advance, the lower levels must be cleared.
Below is an example video of from Introductory Stage Survivor. It shows trander96, who is the Third Hokage, take on Naruto and Sasuke. At the end a congratulatory picture is shown!
