The achievement list for "The Secret Armory of General Knoxx" - Borderlands' third DLC package - indicates the level cap in Borderlands has been raised to at least 61.

Rumors also have it that the level cap raise will go to 70, which sounds plausible. It's unlikely Gearbox would stop on an odd number.

There are 10 more achievements worth 250 Gamerscore. In addition to the level cap raise, it looks like we'll build cars, kill midgets and fight a big crab. Here they are:

• Making a Monster (10)
Build the New Car: Monster

• Athena, Out (25)
Rescue Athena

• Depot Demolition (25)
Destroy the Lance Depot

• Vincible (50)
Kill Crawmerax the Invincible

• Sneaky Little Buggers (25)

• Speed Kills (25)

• Ding! Overleveled (15)

• Ding! Overleveled to 11 (40)
