Trivia

 * The achievement "Student Loans" is a reference to the abhorrent amounts of debt that students coming from college or university receive. Much of that debt from students is from accommodation and the expensive university courses they take.
 * Realistically, a student's student loan once graduating from a bachelor's degree will usually sit between $20,000-$30,000 USD worth of debt.
 * "4 x 10^5" is the scientific notation for 400,000.
 * The number 400,000 itself doesn't have much significance on its own, but "400,000 dollars" is possibly a reference to the Meet the Heavy video, where the Heavy states a calculation about his machine gun, saying it costs "$400,000 to fire this weapon... for 12 seconds". Such a quote has spawned various memes across the TF2 community, and given BTD6 meme culture often linking to content related to Team Fortress 2, it is not inconclusive to assume this phenomenon has a direct connection.
