The Humble THQ Bundle has generated over $4.5 million since launching on November 29.
The bargain game collection, which allows customers to pay as little as $1 for Steam keys for a collection of PC games, has also added Warhammer 40,000: Dawn of War to the mix.
Though the lowest possible payment for all of the games is $1, the average contribution at the time of writing is $5.68. As a bonus, those who pay above the average price receive a copy of Saints Row: The Third, action RPG Titan Quest, Red Faction: Armageddon's Path of War DLC, and now Warhammer 40,000: Dawn of War too.
Buyers can choose how their purchase is divided between the Child's Play Charity, the American Red Cross, and/or THQ.
Over 792,000 punters have purchased the Humble THQ Bundle, which made $2 million in its first night.
