Fun Fact:

TF2 takes place roughly in the 1950s, and Heavy states that it costs $400,000 to fire Sasha for 12 seconds ($2,000,000 per minute; $200 per round); meaning that it costs close to $5,000,000 to fire Sasha for 12 seconds($2,000,000 per minute; $2,500 per round) in today's money, or about $25,000,000 per minute
