With a raised level cap, tweaked enemy AI, and new villains, weapons, and vehicles, The Secret Armory of General Knoxx is Borderlands' biggest dose of downloadable content yet, and it's due out tomorrow.

That's right, those sneaky folks at 2K Games have waited until the day before the DLC drops for the Xbox 360 to announce the release date and price for The Secret Armory of General Knoxx, while PlayStation 3 owners have until the 25th to save up their pennies. How many pennies? In line with the previous DLC, General Knoxx will run 800 Microsoft points or $9.99, depending on the venue.

And developer Gearbox wasn't kidding when they said this would be the largest Borderlands DLC yet. For starters, the level cap is being raised from 50 to 61, giving hardcore players at least another four to five hours' worth of grinding to reach the top.

Then there are all the new additions. Players should be pleased with the addition of ultra-rare, super-powerful weapons, new vehicles, including one all four players can ride at once, and nearly 30 new villains to kill in creative ways. Be warned, however, that Gearbox has also tweaked the enemy AI, so don't expect these new guys to be pushovers.

All of this is wrapped inside a storyline that picks up where the original game left off, tucked inside of an update nearly twice the size of The Zombie Island of Dr. Ned.

It's going to be a very busy week for Borderlands players.
