Xbox LIVE Arcade’s list of offerings is bolstered by two new additions this fine day, with a “revolutionary, simultaneous multi-player Pool action game” called Inferno Pool, and a remake of a classic platformer, Rainbow Islands: Towering Adventure, going for 800 MS Points each.

As mentioned, Rainbow Islands: Towering Adventure is a remake of the classic, trippy arcade game, Rainbow Islands, now on XBLA “with completely new features added! Use your Rainbow Magic to shoot out rainbows to defeat your enemies as well as climb them towards the top in this platform gaming classic! Use your Avatar to personalize the colorful action!

“Play cooperatively with a friend with 2 Xbox 360 Controllers or race to the top against other players over Xbox LIVE. All Areas are seamlessly connected as you climb from the earth to the far reaches of space!”

You can watch the launch trailer for Rainbow Islands: Towering Adventure (well, the Wii launch trailer) to see how it plays, and be sure to check out two additional gameplay trailers for Inferno Pool below, to find out more about that… interesting title:
