The single games portal offers unmetered downloads, gaming and viewing for Internode, iiNet, Westnet, and Netspace customers.
Gamers now have access to more than eight terabytes of files, patches, demos, and content on 600 servers to power favourites including Battlefield 3, Team Fortress 2 and Modern Warfare 3.
Heidi Angove, Internode's Content Manager, said the new site combines the best features of the existing entities and shows the benefits that can be achieved by joining forces.
"The new games.on.net is faster, easier to navigate, and offers more power and content than ever before," said Heidi.
"We now have over 13,000 concurrent player slots, more than double the number we had across the site pre-merge."
"As well as the latest news, reviews and features from the world of gaming, games.on.net provides a huge cluster of rock-solid, lightning fast servers to play them on."
The relaunch of the super-powered games.on.net coincides with its tenth anniversary. The site was originally established in July 2002 in an Adelaide backyard shed.
