Lockdown is the first entry in the Rainbow Six series to feature graphics effects which includes normal mapping and specular lighting, as well as physics objects. Advanced graphics were available only on the PC version.Lockdown’s gameplay is more action-oriented than that of its predecessors, and features a number of departures from the more tactical elements of the earlier games. As a result, gameplay is much closer to that of a generic first-person shooter, instead of the tactical shooter gameplay of previous titles that made the series as popular as it was.
