Let's Play Sonic the Hedgehog 2 Part 4
1Taking on Acts 1,2,and 3 of Metropolis Zone,plus getting through the Sky Chase and Wing Fortress Zones. Metropolis Zone is basically the Scrap Brain zone of this game. Lots of things to kill you here,including lava,spikes,and exploding starfish things that blend into the environment. The crab enemies are difficult to deal with due to their wonky hitbox,either ignore them or spindash them if you're far enough away. It's also almost impossible to dodge the attacks from the mantis things,when they toss their blades at you. Robotnik/Eggman will fight you at the end of Act 3. Every time he's hit,he releases a mini version of himself that you must kill. When his defenses is gone,he'll use a laser as a desperation attack. It's incredibly tough to land a hit on this boss without getting hit yourself,so I highly recommend coming into this fight as Super Sonic to end the fight quickly. Sky Chase Zone is pretty simple,just don't go Super or Tails can't keep up with your speed. Wing Fortress can be difficult and confusing to navigate as well. Wait until you reach the upper deck to turn into Super Sonic,then you'll be able to reach the boss easily.
