First Strike is faithful to the original franchise when it comes to graphics. Nothing looks particularly impressive, but then again, the game's not exactly trying to push the technical limits of the iPhone. The cutscenes look good, but most of them look sped up and don't last any longer than about three seconds. First Strike's presentation leaves little to complain about, as well; sepia and camouflage is really the only color scheme needed when it comes to old wars.
First Strike has a really good soundtrack that makes up for the somewhat subdued sound effects. However, it's hard to fault the sound effects for two reasons: the iPhone can't handle booming explosions and the like due to the functional but admittedly weak speakers. Also, the occasional "pewpewpew" sounds were present in the original games, if memory serves me correctly.
