A fourth video developer diary for Operation Flashpoint: Red River features the developers on Codemasters' upcoming military shooter sequel discussing changes to the game's command radial. They explain the effort they've put into simplifying its use, which now involves two layers, rather than three, and its greater degree of context sensitivity compared with Dragon Rising, with principle designer Tim Browne confirming that this is console-influenced by describing how it can now be operated by "two thumb movements." Word is the radial can now be operated while the player is moving, and that its design and some included tutorials are meant to be less intimidating to new players. They also discuss the addition of radar, a new waypoint system, graphic enhancements, and other elements intended to enhance the player's immersion. The embedded trailer follows.
