With February being the final month of PlayStation Plus offerings for PlayStation 3 and PlayStation Vita, Sony may be conscious of the fact they need to offer another enticement for people to consider subscribing to the service. As such, they've come up with a new offer. For the price of £49.99 or regional equivalent, players can purchase a 12 month membership and get Tom Clancy's Rainbow Six Siege for free. The catch is you have to be a completely new member to qualify for the offer.Available now, the offer allows all PSN accounts that have never had an active PlayStation Plus membership to get the free game if they subscribe to PS+ for 12 months through the PlayStation Store. Accounts that have never had a paid subscription but have made use of the 14 day trials still qualify for the offer. While the PS+ membership will activate upon purchase, the game will not be added to your account until up to 96 hours later.If you're one of the qualifying accounts and you wish to make use of the offer, you can find links here:We've got the full list of Tom Clancy's Rainbow Six Siege trophies - check the list for guides to unlocking them.
