2K Games' mobile holiday sale cuts prices on six iOS games, including Borderlands Legends ($.99) and NBA 2K13 ($2.99).
If you haven't bought the BL game, don't. I can't recommend it...even for a dollar. I really wanted it to be good and gave it a chance, trying to stumble around it's terribad controls and UI for a few hours.
It just doesn't play right and doesn't feel like Borderlands at all.
Just my two cents. Though 99c is a good opportunity to pick it up on the cheap and tell me all the reasons I'm wrong :(
