You will need the Spinal Character DLC for this achievement. You can buy this from the in game Ki Store under the Premium tab. Once you have Spinal as a playable character, go to the main menu, select LOCAL PLAY and SURVIVAL. To make it easier, switch to BEGINNER difficulty, but the achievement can be unlocked on any difficulty setting. Leave SKIP AHEAD set to 0(0 KP) and press A. Select Spinal as your character and any skin you want for him. Once you complete your first match the achievement will pop during the Fight Results screen. I suggest continuing on to defeat 10 characters in one sitting to also net yourself the Spinal's Endurance achievement, which will pop during the Fight Results screen after winning your 10th battle. Depending on how you play, you could end up unlocking 30 fight titles during these ten battles and get the Novice Spinal Achievement as well! If you are good enough to unlock 50 fight titles during these battles, go to the Ki Store and purchase your newly unlocked Skin Color 3 for Spinal to get the Stylish Spinal Achievement as well! If you are only one or two shy of 30 or 50, go to Local Play and select Versus. Play against a CPU opponent and win to get the Sparring Spinal Achievement.
