This Prequel lacks the feeling of its Sequel predecessor but it's still a great game with new features.
The graphic and the sound of the game are same as they were in the first game since it's a EP of course but there are lots of new thing besides the story:
The US will get 3 new weapons: (M-14 W\O Optics and Silenced Sten MK-II)
While the North Vietnamese get 4 new weapons: (Vz 61 "Scorpion", SVT -40 W\O Optics and Degtyarev LMG).
The game has only 5 missions but as you know every mission divided to 2 or 3 sub-mission but since it's a EP the game is very short compared to the first game...
The MP still suffer from Bugs issues but this game is recommended for the people who enjoyed from the first game and wants to know more about the plot.
