If you missed the first Amazon pre-order deal for Halo 3: ODST, or perhaps you've just been putting off ordering the game, now is your chance to save $15 off the price of the game.

Arcen Games has just patched their co-op RTS, AI War, to version 1.301.  With it brings a host of improvements to both the interface, ship graphics, new units, new network code and a host of other tweaks.  Considering the game claims you can have 30,000 units in a battle at once I'm sure the net code needs to be very neat and tidy for a lag free co-op experience.

When purchasing headphones, I will rarely if ever even glance at ear buds for any reason. To me, ear buds are the cheap inserts that come with products, mildly uncomfortable with sub-par sound. That is, until I tried out the Tritton AX Ear buds that I received at the Blue Skittle Party at PAX. Starcraft was my first test with its phenomenal in-game sounds coming through loud and clear, then on a Nintendo DS to see if they worked just as well on the road.

Is the music game genre oversaturated?  Some might say yes.  I'd argue otherwise; there's still plenty of good music out there that isn't available in video game form.  In any event, we have some details about Harmonix's upcoming cutesified LEGO Rock Band.  Iggy Pop will be appearing in the game, as the tutorial voice, and also in plastic action figure form, as you an see above.  Iggy's song "The Passenger" will be in the game's song list.

Stardock has announced that preorders are now being taken for the upcoming micro-expansion for Sins of a Solar Empire entitled Diplomacy.  The DLC adds faction status and trade pact options within the game, as well as the ability to issue new missions to other players.  The biggest addition is a brand new diplomatic skill tree which adds over thirty technologies.

Spelunker HD is already available on the Japanese PlayStation Network, and the remake of the classic NES game has garnered some fairly solid buzz.  Now we have word that the game will be making its way stateside, along with the included 6 player online co-op mode!

Remember how pissed off you were when you found out you could only get Juggernaut for Marvel Ultimate Alliance 2 if you preordered from Gamestop?  Remember how you wanted to smash your head through a wall in anger?  Please remain calm, we're about to tell you how you can stick it to the man and get Juggernaut for yourself without setting a foot inside Gamestop.

After almost 4 months of waiting, PlayStation owners will finally get their hands on the three player co-op title Trine.  Developed by FrozenByte Software, the game is a physics based puzzle/platformer that puts players in the role of the Wizard, Thief, or Knight.  We really enjoyed the PC game, and have high expectations for the PSN version - we just wish the extra time was used to add online co-op.  Sadly, it's still missing.  Last we heard the game is priced at $20.  

We got our hands on SOCOM U.S. Navy SEALs: Fireteam Bravo 3 at PAX, confirming 4-player co-op both online and locally (ad hoc) and thoroughly enjoying our limited time with the title. We did not have a release date, however.

Lats spring, to coincide with the most recent (and awesome) Trek film, Star Trek D-A-C hit Xbox Live Arcade.  A team-based shoot em up, with a decidedly old school arcade feel, we didn't think too highly of the game, particularly the co-op.  Now the game is headed to release on the PC and the Playstation Network, in November, just in time for the DVD release of the film. 

For those of you that pre-ordered Uncharted 2: Among Thieves, you now have access to an exclusive beta of the game which features a few multiplayer modes.  Among those modes is the new co-op mode called Gold Rush.  The goal of this mode is to steal a treasure and bring it to a capture point, all the while avoiding waves of enemies.  Each successive capture increases the difficulty and number of enemies.  Like other survival and Horde type mode, we found this to be quite entertaining.  

It's time the PC got some balls, Madballs that is.  Launching today on Steam, Madballs in...Babo Invasion brings four player co-op action to a whole new set of gamers.  The PC version of the game is almost identical to the Xbox Live version, though there's a few tweaks under the hood and more graphic options.
