Computer & Video Games has a Rainbow Six 4: Lockdown Q&A today, asking game designer J.P. Cambiotti about the game's features and the reasons they are changing this franchise. Here's a bit on why they are making the game "more accessible".

Cambiotti: In the past Rainbow Six got criticism for being too difficult, too hard to get into - the one shot, one kill hardly makes it very instant. Although we've kept that in for the hardcore fans, we've also tried to open it up to people who haven't really picked up the series before. So you've now got aiming assistance and a 'save anywhere' feature. Plus, there's a sniper vision that's more of a departure from the regular Rainbow fare [enemies are easier to spot]. But despite these options, there's still a lot of the 'room playing' and the tension generated by one-shot kills that fans have come to expect.
