This week's PlayStation Store update is pretty big, and it includes several new games, videos, and free add-on downloads.

There's four downloadable games this week, and two of them require the PlayStation Eye. Trials of Topoq is a rolling marble type game controlled by your bodily movements. It sounds complicated, but its quite fun once you get the hang of it. The other, Mesmerize: Distort ($1.99) isn't as much a game as it is a virtual acid trip. They call it an "interactive experience."

The house racing game Toy Home (629mb) is now available for $9.99, as is Snakeball. In Snakeball, you "glide across the dazzling disco floor on your hoversnake, collecting balls and scoring goals." Wow, sounds pervy!

Most of the add-on game content is free this week. There's the free Folklore content we mentioned earlier, as well as a free MotorStorm Holiday Skin and a free Guitar Hero III song (“We Three Kings”). High Stakes: Poker Edition has two new free game add-ons as well.

$7.99 will get you the new Warhawk: Omega Dawn Booster Pack, which adds a new KT-424 Combat Dropship and the night time Omega Factory Battlefield. $1.99 will buy you new Rock Band songs from Weezer, Radiohead, or The Pretenders.

Lastly, as far as games go, the PS1 classic Warhawk is available for $5.99 for PSP and PS3, and the Blacksite: Area 51 Demo is available as a 931mb download.
