Sony has some treats in store for US PlayStation Plus subscribers this week. Anyone who spent their childhood putting fools in headlocks in Double Dragon on NES will want to check out Double Dragon Neon, which will be free to PS Plus users from tomorrow, November 11.Scott Pilgrim vs. the World: The Game will also be free, and Jet Set Radio will get a 10 per cent discount. PS Plus users will also be able to pick up Max Payne 3 for $40.49 - a 33 per cent discount on the usual $60 price (regular PSN users will get a still worthwhile 25 per cent discount).
