In the next four weeks, OlliOlli (1/21), Dragon Ball Z: Battle of Z (1/28), Dustforce (2/4), and TxK (2/11), will go on sale. You can get any of them for 20% off during their launch week if you're a PlayStation Plus member. Additionally, if you buy two of four, you get a $3 credit. Three of four nets a $6 credit. Buy all four and get $10 back.
Not a bad deal, even for the launch week sale prices. OlliOlli is pretty great -- catch our review tomorrow. And only one port (Dustforce)! Plus, TxK is a sequel to the Atari Jaguar Tempest 2000, from its original creator. I need that trippy neon in my eye holes.
