Here's how it actually works:
* Unlocking G1 Ironhide: You need to complete the "G1 Ironhide Challenge" in the game's single-player campaign. This challenge typically involves completing a specific mission or set of objectives with a certain character.
* Bumble Bee Boosts: Bumble Bee boosts are a special ability in the game, but they're not directly related to unlocking G1 Ironhide. You may need to perform some Bumble Bee boosts during specific challenges, but it's not a general requirement.
To find out the exact details of the G1 Ironhide challenge:
1. Check the in-game menu: Look for a section that lists challenges or achievements.
2. Consult online guides: Websites like GameFAQs or IGN often have detailed walkthroughs and information on unlocking characters.
Good luck unlocking G1 Ironhide!
