In light of Comic-Con, the PlayStation Store is having a sale on all things superhero-related. The Supserhero Sale is already live, and will be available through July 13, 9:00am PT.
It looks like the sale is extended to general supernatural franchises as well, rather than strictly superheroes. In addition to deals on LEGO Batman, Injustice, and older Batman: Arkham games, there are several Mega Man, Mortal Kombat, Saints Row, and inFamous titles on sale as well.
Nothing too crazy cheap for PS4, but the LEGO games are always a good time. PS3 owners can get some pretty sweet deals through PS Plus though, such as Batman: Arkham Asylum and Origins ($6.00 and $8.00, respectively), Devil May Cry HD Collection ($9.00), and Mega Man 9 and 10 ($4.50 as a combo) if they haven’t already taken advantage of previous sales and PS Plus promotions.
