Two days after launch, more than 875,000 gamers responded to the campaign by downloading Duty Calls, and just seven days later that number climbed to two million, four times our original estimate. So great was the response that additional hosting fees were required to meet demand. Videos of gamers documenting their Duty Calls gaming experiences garnered over four million views collectively, and there were more than 150 articles published generating further conversations and comments about Bulletstorm. Duty Calls cost $0.17 per person, but when accounting for the broader estimated total audience reached, that cost shrank to $0.01.
