Here we go again! Another Metal Gear Solid reveal trailer is going to throw us into another painfully long development cycle, and we're going to eat up every second of it. It seems no matter how old the series or its protagonists get, or how often the series gets one upped by its younger stealth rivals, the next Metal Gear Solid is always the biggest thing in gaming. Metal Gear Solid: Ground Zeroes is more than likely to continue the tradition.

The 11 minute demo released during the 25th Anniversary party this weekend shows off a group of soldiers claiming to be an army without a nation and a young mysterious boy trapped in a cage being groomed into a soldier. Snake, perhaps?

Big Boss has aged quite a bit since Metal Gear Solid 3. He doesn't look as old as Old Snake, but he's definitely up there with gray peppering his hair and beard. He appears to be on a recon mission to investigate these rogue soldiers. My guess is once he kills the Red Skull there, these wayward warriors will hire him to become the leader of Outer Heaven by the game's conclusion. Just a guess, no spoilers.

The latest theme song can also be heard in the background, and Konami obviously spared no expense tapping influential film composer Ennio Morricone to write it. It's no Snake Eater, but we'll see how well it falls in line with the overall entire game.

For a gameplay trailer, only a minute of actual gameplay begins very close to the end at the 8:45 mark. It's brief and doesn't exactly show that much, but it does show off the impressive power of Kojima's new FOX engine.

Konami has said Metal Gear Solid: Ground Zeroes will be a current generation game set for release on the PlayStation 3, Xbox 360, and PC. This will make it among the last huge titles for this cycle of consoles if it doesn't get pushed back. Kojima also confirmed that this is a prologue to Metal Gear Solid 5, not Metal Gear Solid 5 itself, when he is expected to bring back Solid Snake.
