Ah. First off let me just say that this Weekend Warrior is a particularly short one. But hey, we still heard some good PSP news over the week. Konami's finally announced that they're working on English demos for Metal Gear Solid: Peace Walker, and for those that can read Japanese there's a God Eater demo on the way. Best news so far this week for me, though, is BlazBlue PSP. Hit the jump for this week's PSP Weekend Warrior edition.

This week's PlayStation Store Update is now live. The controversial Rock Band Nirvana track pack is here, so all you rockers out there are sure to enjoy the animated Kurt Cobain rockin' it out alive and well in this game. It's a double treat too as Nirvana drummer, Dave Grohl's own band, Foo Fighters, also shares some love in this week's release. Other big releases include Dissidia Final Fantasy for the PSP, Trine's PS3 demo and Ghostbusters: The Video Game on the PSP. Full list awaits after the jump.

It's been a while since we last heard about Namco Bandai's God Eater. If you know Japanese (or have enough trust in your ability to navigate a menu without understanding a thing about it), you'll get to do more than hear (or read) about it soon. You can get to play the demo.

Heads up guys! The latest US PlayStation Store update is now available. This weeks lineup includes a bunch of PSP game sales, new game demos including Fat Princess and Pro Evolution Soccer 2010, the usual game add-on contents, new Minis and a bunch of classic as well as some brand new downloadable games for the PS3 and PSP that includes LocoRoco: Midnight Carnival and Crystal Defenders.

Here's some nifty Halloween week treat for you all Call of Duty: World at War (PS3, Xbox 360, PC, Wii) fans. The Map Packs will be offered at a 50% discount on both the PSN and the XBL this week. all the way till November 1st.

Crimson Room: Reverse is a PSP port of the popular Crimson Room flash game where players have to find their way out of a locked room. Japan already got it last year, and it looks like the US will be getting it as well.

Here's some good news for those who went out and got a copy of the delightfully demented PS3 and Xbox 360 hack-and-slasher, Fairytale Fights (and also those who have yet to do so). Playlogic Entertainment will be giving away free DLC for the game.

One of the new things being introduced in LocoRoco Midnight Carnival is the ability for up to four players to race against each other across a level. The game's already coming out on PSN this week, so to give you a better idea of how the multiplayer component goes, here's a video.

So what transpired in the world of Sony's PS3 this week? Nate Drake's newest adventure is certainly off to a good start. And then there's word that the PS3 is continuing its newfound sales spurt in the land down under. Oh, and here's a no-brainer: rumblings about new entries in two of the PS3's biggest franchises have started to trickle out from the rumor mill. All in all, another good week for the PS3. Well, except maybe for that one particular console they threw into the Bravia. It didn't seem to get too banged up though.

The latest round of update for the US PlayStation Store is now available. This weeks lineup includes the usual game add-ons, a few price drops, three new game demos including the much awaited Ratchet And Clank Future: A Crack In Time, tons of downloadable PSP games and a pair of Oddworld PSone classics as well as some brand new downloadable games for the PS3 and PSP.
