Sonic Robo Blast 2/YMMV

• Crowning Music of Awesome: Arid Canyon Zone's theme
  • The music from both acts of the Egg Rock, but Act 2 appears to be a fan favourite.
  • Cloud Palace Zone's theme, also used in Neo Aerial Garden Zone.
• Game Breaker: Tails can easily fly through irritating bottomless pit sections... But even he has trouble in Egg Rock Zone.
  • Knuckles's gliding and climbing abilities can similarly be used to bypass a lot of platforming sections.
• Goddamned Bats: Sharps. They are blue hockey-puck things that turn red with a loud noise when they see you, and then they chase after you at very fast speeds while invincible, and the whole "get hurt and attack with temporary invincibility" thing won't work. They turn blue again after a while, but you're probably still collecting your spilled rings.
  • The Buzz enemies from Techno Hill Zone are also fairly annoying, with their tendencies to pop up out of nowhere and knock you off platforms.
  • Egg Guards, if you're not playing as Knuckles. Knuckles can smash their shields with his strength, but Sonic and Tails are forced to approach from the back, which is much harder than it sounds. And inexperienced players might not notice that wrecking the shield doesn't quite wreck the robot...
• Nightmare Fuel: Never, ever, ever type "TUNES 20" into the console. Just don't.
  • The original intent for Space Countdown sectors was to turn off all sound effects and change the music to TUNES 20. This was cut for numerous reasons, Nightmare Fuel being just one of them...
  • Incidentally, the sound effect came from MDK2, during a brief trip outside your pressurized space station, the Jim Dandy. It wasn't quite as terrifying there.
  • The infamous drowning theme makes a comeback and is, as usual, quite terrifying.
• That One Level: Egg Rock Zone.
  • Justified, in that it's supposed to be preceded by two more acts for pre-existing zones, another zone, and a possibly one-act zone. The game is still in development, but priorities shifting to the multiplayer aspect put single player stages on low priority.
  • But even after that, ERZ will still be the hardest level in the game, unless it somehow turns into a Breather Level...
  • Word of God has stated that ERZ is supposed to be that hard.
