Here's why:
* The game was discontinued. "LEGO Hero Factory: Brain Attack" is an older video game that was released in 2010. Since then, it has been discontinued, meaning it's no longer being sold or supported.
* Digital copies are scarce. Even if you could find a used copy of the game, you wouldn't be able to access the "Creep Crusher" digitally.
* No in-game purchase. There wasn't an option to purchase the Creep Crusher separately within the game.
What you can do:
* Search for used copies: Your best bet is to look on online marketplaces like eBay or Etsy for used copies of the game. However, these will be rare and might be expensive.
* Emulate the game: If you're technically savvy, you could try to emulate the game on a computer. However, this can be challenging and requires finding the game's ROM file.
* Explore other LEGO Hero Factory games: There are other LEGO Hero Factory games available, such as "LEGO Hero Factory: Invasion from Planet 8" and "LEGO Hero Factory: Breakout." While these may not feature the Creep Crusher, you can still enjoy the LEGO Hero Factory experience.
I hope this helps!
