Hot and steamy, we're going to start listing media we add to the site on a daily basis. Not everything is linked in stories, and would be missed otherwise. Today we have screenshots from FlatOut: Head On, Motorm4x, Switchball, Unreal Tournament 3 and World Puzzle along with videos from Need for Speed ProStreet and Resident Evil: The Umbrella Chronicles. FlatOut: Head On will race onto the PSP next year. Six small shots are available here. Prague-based The Easy Company is working on the PC off-road racer Motorm4x. Four new screenshots right here.

The puzzle-filled labyrinths of Switchball and the logic challenges of Word Puzzle represent this week's Xbox Live Arcade Games. Both arrive on the download service this Wednesday, November 7, and both will sell for 800 Microsoft Points ($10). The mazes of the Atomic Elbow-developed, Sierra Online-published Switchball require players to alter the properties of their ball to clear obstacles, such as barriers vulnerable to the Metalball or what Microsoft describes as "physics based death traps," which mandate the Airball. In addition to five environments, the game packs two-player online co-op and eight-player racing. According to publisher Microsoft, InterServ International's Word Puzzle contains "a whole host of synapse melting challenges." It includes five different game modes, allowing up to four local or online opponents to compete for word searching glory, and InterServ promises an abundance of downloadable word packs to keep the action fresh.

We reported on the release date last week, but Microsoft has now officially confirmed that PomPom Games' top-down room-based shooter Mutant Storm Reloaded will be this week's Xbox Live Arcade title. Including both online and offline cooperative multiplayer, Mutant Storm Empire and its cacophony of mutant screams and robot death cries hits the service on Wednesday, October 31, selling for 800 Microsoft Points ($10). Along with Mutant Storm Empire, the company also announced that the final contestants of the Doritos Unlock Xbox Challenge are available to play at Snack Strong Productions. Up until November 18, players can vote for the one game they want to see transformed into a full-fledged Xbox Live Arcade title, which will be released for free in summer 2008. As for upcoming Xbox Live Arcade releases, Microsoft issued the following list of games that will arrive "in the next few weeks":

• N+ / Slick Entertainment, Metanet Software
• Screwjumper! / Frozen Codebase - Screens
• Shrek-N-Roll / Activision
• SpongeBob SquarePants: Underpants Slam / THQ

For this week's ShackCast, Remo spent some time hands-on with Super Smash Bros. Brawl (Wii) and several of its new characters--Pit from Kid Icarus, Meta Knight from the Kirby series, the new Samus and her Zero Suit form, and the just-revealed Sonic the Hedgehog. Nick was at Epic's offices checking out Unreal Tournament 3, which he feels is underrepresented by its recent demo. Carlos met with Sierra to check out several upcoming PC and Xbox Live Arcade downloadable games; some--such as Aces of the Galaxy and Commanders: Attack of the Genos--are promising, and some--Battlestar Galactica--are not. Plus, all of us played through Portal and loved it, because it is lovely. Finally, we discuss Double Fine's new game announcement and Electronic Arts' acquisition of BioWare and Pandemic Studios.
