New to the PlayStation Store this week are the usual lineup of Rock Band downloadable tracks, new Turok and Unreal Tournament 3 map packs and downloadable favorites at newly discounted prices.

Rock Band owners can now get their grubby mitts on the Boston track pack, which includes master tracks of "More Than a Feeling," "Hitch a Ride," "Peace of Mind," "Rock and Roll Band," "Smokin'," and "Something About You." The tracks can be purchased individually for $1.99, or in a bundle for $9.99.

Epic Games' Unreal Tournament 3 will be updated with a new map pack, available free of charge. The three-map pack includes Morbias and Facing Worlds, two classic maps from previous UT titles, as well as the brand new CTF map Searchlight.

Unreal Tournament 3 has also been patched to version 1.1. The update, which includes a variety of tweaks and fixes, will automatically download when starting the game.

The previously announced Velocirapter Map Pack for Propaganda Games' Turok is now up for download at a $4.99 price point. The pack includes two new multiplayer maps, one new co-op map and two relit versions of popular maps already included with the game.

Two games are now available on the PlayStation Store at a reduced cost. Incognito's multiplayer-only Warhawk will be priced at $29.99 until April 15, $10 off of the original price. Thatgamecompany's flOw is now available in a bundled form, which includes the full game and its expansion pack, for $8.99.

And finally, a single, lonely demo makes its debut this week with Irem's tactical RPG R-Type Command (PSP), downloadable free of charge from the PS3 storefront or the PlayStation Store for PC. The game is scheduled to hit retail shelves on May 6.
