Nearly 7 months after release, Gearbox is finally upping the BL2 level cap to 61. Added bonuses being a third playthrough and pearl weapons.
Bad news? Level cap increase will cost $5, "free" to season pass holders (like myself). 3rd playthrough will be free for all.
Also included with the free 3rd playthrough update...is...an update to the Black Market! More backpack storage. More bank storage. More ammo. Finally something to do with your 99 Eridium!
