Master the tricky TunnelBot and Dr. Robotnik's Jet Drill Machine in Sonic & Knuckles Act 2. Get the strategy to spin dash through walls and avoid crushing scenery!
Alright, let's get through this tricky section of Sonic & Knuckles! We've got the TunnelBot to deal with first, and then it's onto Act 2 with some classic Robotnik action.
TunnelBot Encounter:
When the TunnelBot shows up, it's going to cause an earthquake by drilling upwards. It's super hard to dodge the falling stalactites, so keep your eyes peeled. Don't worry about the other debris, it's harmless. When the TunnelBot comes back, wait until its drills are pointing straight up before you go in to attack it.
Act 2 Walkthrough:
You'll start Act 2 by needing to Spin Dash through a wall. After that, climb up the hills using the pulley lifts. Head right and Spin Dash through another wall. You'll see Robotnik here – you can hit him if you want, but it doesn't actually change anything for the boss fight later, so don't stress about it. Just keep heading right and go down the hills. Continue right and use a Spin Dash to reveal two platforms. Drop down and enter the passageway; there's a Giant Ring in there for you!
Now, head back up and go right. You'll need to use the spinning top contraption to keep moving forward. Use another Spin Dash to uncover two more platforms. Go left, climb up the hills using the pulley lifts again, and pass the Starpost. Follow the directions on the signs. You'll find an arrow machine; hit it three times to reveal two more platforms.
Keep heading right and use a Spin Dash to uncover two platforms. Run down the hill to your right. You'll encounter a flying spinner – use it to break through the walls ahead. Continue right and Spin Dash through another wall. Hit the arrow machine three times, and it'll drop you down.
Head left and go past the next Starpost. Use a Spin Dash to reveal a hidden passageway. After you see Robotnik again, Spin Dash through the walls and run down the hills. Here's a critical part: as the scenery starts sinking, you need to keep running non-stop to avoid getting crushed and losing a life! Once you reach a Starpost, go left and Spin Dash to uncover two platforms. Head right from there, and you'll meet the boss.
