For brand-new character, the price will remain the same. You’ll be able to pick up new Australian operators Mozzie and Gridlock, for example, for 25,000 in-game Renown, or 600 R6 credits (about $5, or £4). After 12 months, that price will drop by about 20%, to 20,000 Renown for 480 R6 credits.
Two full years after their release, picking up a character will only set you back 15,000 in-game currency, or $3 in real money. That’ll drop even further after three years – some of the earliest additions to the game’s roster will now only cost 10,000 Renown, or just a couple of dollars in real money. For the health of your wallet, these are pretty minor changes – just three dollars over the course of three years – but the changes should be major timesavers.
