For the next mission, head to the South Park Senior Center and meet up with Tupperware and Wonder Tweek. After the scene, you’ll be performing in front of the senior crowd. Just follow the button prompts as they appear. Once you get to the flugelhorn part, improvise as needed until the old people recognizes you. You’ll have to fight them afterward.
The combat party will have Wonder Tweek, Tupperware and Professor Chaos as fixed members. The objective is not to defeat all enemies but to reach the exit in the far left side of the screen. Take note that the defeated old people will be revived indefinitely so it’s impossible to whittle down their numbers as you push through towards the exit. Fortunately, they’ll start on the right-side of the screen when they revive. Basically, you still have to defeat them to clear the fight, preferably using charge attacks to quick move forward. Most of them have limited movement range but some of them can throw nasty stuff that can gross out the target. Like before, having the Time Fart Summon will help a lot in breaking through the elderly line.
If you haven’t tried out having Tupperware in your team yet, you’ll get a chance to take advantage of his gadgeteer skills in this battle. His Hot Swap power allows him to swap places with an ally while also getting protection. This will be a great way to protect low HP and squishy allies such as Wonder Tweek. He can also deploy an auto-turret which will stay in the battlefield until it is destroyed. Since it has its own HP bar, enemies can shift their attention to it, giving your team mates more chances to move or attack strategically. It can also attack enemies in a straight line in both directions.
Make sure to have Tweek heal up allies whenever he can, especially those inflicted with HP-draining status ailments. It’s also recommended to use AoE and status ailment attacks to quickly defeat the elderly blocking your path. Once the enemies in the left side of the field has been defeated, continue moving to the exit. Have Tupperware deploy his turret when ready to serve as both sentry and decoy. If your allies are already in the escape point, make sure to have them end their turn there in order to win. Your past self is not required to join you in the escape point in order to win this battle. After all allies reach the escape point, you’ll receive the Seal of Freedom Artifact, $4.27, and 120 EXP. Mission complete.
