While the PC gaming world has been holding its breath for the imminent arrival of the yearly Steam summer sale and console owners are gearing up for both PlayStation Network and Xbox Live sales this week, Green Man Gaming (GMG) has gotten a jump on the competition. The online games retailer today launched its own summer sale, complete with a hell-themed site overhaul.

As part of its “666” sale, GMG will be offering six big game sales every six hours for the next six days. The first six deals of the sale include the new Star Trek game for 66% off, Resident Evil 6 for half-off, and Borderlands 2 plus the Borderlands 2 DLC Season Pass for 75% off (together only $15). The sale began at 11 am EDT, and will switch over to the next six deals at 5 pm. As most of the titles bought on GMG require a Steam account, this 666 sale can be thought of as an early Steam sale.

“Our 666 sale is Green Man Gaming’s most ambitious and twisted sale yet.” said Darren Cairns, EVP of marketing at GMG. “6 fiendish deals, every 6 hours for 6 days, makes our Summer Sale as hot as hell.”

In addition to the sale prices, GMG is also offering an additional 10% off of 666 titles with the use of a voucher code located on its “Hot Deals” page.
