Tien's Sacrifice

Piccolo vs. Android 17: You'll start by controlling Piccolo against Android 17. Don't worry too much about his attacks; Hell Storm is just a big Ki blast, and Savage Combo is a standard two-part melee attack that might track you a bit. The main thing to watch out for is Android 17's Barrier, which makes him invincible. If you get too close, it'll even push you back. He doesn't move much while using it, so just avoid it and wait for it to drop.

Goku vs. Semi-Perfect Cell: After the fight with Android 17, the scene shifts to Cell absorbing him and becoming Semi-Perfect. Tien bravely steps in to hold Cell off with Tri-Beam, giving Goku the chance to teleport in. Now, you'll fight Cell as Goku. He's using moves you've seen before, like Kamehameha, Guided Kamehameha, and Special Beam Cannon. His melee attacks, Impact Smash (two hits) and Sonic Blow (three hits), are also familiar. Cell is a bit more aggressive this time, using more Super Attacks, but he's still manageable. Remember to transform into a Super Saiyan to deal more damage, but keep an eye on your Ki gauge because that transformation drains it constantly.

The Sacrifice: After your battle with Cell, he manages to grab both Tien and Piccolo and escape before Goku can do anything. This is Tien's sacrifice, buying time for the others.
