In some missions you must fight without using the radar, which is essential to locate your enemies. In other missions you fight in a nebula, which means visibility range is way down and you fly partially blind. You will also have a chance to pick from multiple missions, not just from plot choice. There are also alternative guns that are may be available in the crafts you fly, which introduces even more variables. In some missions you will need to send a separate team toward a different objective, and your choices will affect that mission's success.
Explosions are now more spectacular.
Missile launches are now accompanied by missile trails for easier tracking and evasion, and the ships and fighters themselves look as good as ever. Between Flights Between flights you wander about the ship you are on and interact with various characters onboard. You will see more panning and zooming which makes the whole thing fell more like a movie. The acting in WC4 is good, as good as WC3 if not better. Mark Hamill John Rhys-Davis, Malcolm MacDowell, etc.
