Yes, the PSN site will have a section for ‘Free to Play’ games on the Deals page. Otherwise, you can sign up for PS Plus to access a digital game library, Ubisoft+ classics, and take advantage of free trials.
PSN does not offer an exclusive student discount at this time. The brand may release one in the future, and you can take advantage of the PSN promo codes and vouchers featured here at NME in the meantime.
To redeem a PSN voucher, log in to your account or sign up. Add the games or items you wish to purchase to your cart. A pop-up summary will appear on the right side of the page; paste your PSN voucher into the ‘Discount Code’ box above your payment methods.
