Survival is a mode where you fight as many opponents as possible without losing. If you take damage during a match, only a small amount of it will recover for the next match. This mode made it's debut in Tekken 2 and has been in every Tekken game since.
The opponents get harder every match. However, certain cheap tactics can still allow you to reach over 100 wins. If you get a high score, you will be allowed to sign your initials. Otherwise, you'll get a message saying something along the lines of "You need more practice".
