Sierra have announced a raft of new titles for the Live Arcade, detailing first Switchball, a physics-based puzzle title due out on the download service this summer.

Commanders: Attack! is a turn-based battle offering, and we're also promised (the previously confirmed) Battlestar Galactica, which is based on the Sci-Fi Channel show. The latter two titles will be released this autumn.

"We appreciate the opportunity to create original IP in the space, as we did with Assault Heroes, as well as the opportunity to reinvent catalog titles such as with Ultra Minigolf Adventures," commented David Haddad, VeePee of Sierra Online.

The Online boss is also promising Sierra titles for the Network, but no releases have been detailed as yet. More soon.
