Whether you own an Xbox 360 or a PlayStation 3, you've got a lot to keep you busy today, as several companies are releasing both add-ons to their current hits and downloadable demos for upcoming games.  Here's the list.

First up is Dead Space 3: Awakened, the latest single player add-on to that series, featuring a lot more spookiness as you shoot your way through Necromorphs.  You can get it for $9.99 (800 Microsoft points).

Next up, PlayStation 3 owners can download their additional 30 VR stages for Metal Gear Rising: Revengeance, which are available free of charge if you bought the game.

On both consoles, those of you who thoroughly enjoyed the Square Enix open world action game Sleeping Dogs can rejoice over the addition of the new Year of the Snake story pack, featuring more missions and enemies to take on.  It'll set you back $6.99, or 560 Microsoft points.

As announced yesterday, the Scott Pilgrim vs. the World add-on with online multiplayer and new character Wallace will also be available today for $4.99 (400 Microsoft points).

In the new demo department, Tecmo Koei is bringing Ryu Hayabusa back to cut things up in Ninja Gaiden 3: Razor's Edge; and EA is putting a big push behind its forthcoming action tour-de-force Army of Two: The Devil's Cartel, as you can try out that game as well at no charge.

Last but certainly not least, be sure to check out Capcom's Darkstalkers Resurrection, which packages together two of the best games in the ongoing monster-filled fighting series.  It's priced at $14.99, or 1200 Microsoft points.  It'll be on PSN tonight and Xbox Live tomorrow.

A lot to download, so you better get to it!
