Men of Valor came out in 2004 and boy have things changed in the last 16 years.
You play as Dean Shepard, a marine soldier in the Vietnam war and you follow Dean and his squad mates through 13 missions that ends with the onslaught of the Tet Offensive of 1968.
The gameplay is simple and like Call of Duty, but a lot less refined and much slower. The running speed in MoV kinda feels like sneaking in comparable games. Most of the time, Dean and the others are in the jungle, surrounded by thick foliage and tree lines which makes for a rather odd surrounding in this traditional corridor shooter.
Enemies are dumb as bricks and pops out from the bushes, seemingly at random which makes for many frustrating encounters where an enemy comes straight out of nowhere (there is no way to predict which way they'll come from besides trial and error) and if you are unlucky, a VC gunman will chip away half your health bar with one shot. Most of the times however, the enemy is too dumb to even run in the right direction and starts spraying in random directions.
The plot and narrative of MoV are a lot better than the gameplay, especially the written correspondence between Dean and his father discussing Deans experience in 'Nam and his parents fears and worries regarding their son thay plays between missions. Likewise, when Dean dies (and he does plenty of that), you are treated to a letter of death notification sent by the US Military to Dean's family that describes how he fell (this changes between missions). It gives a depth to an otherwise hollow experience.
The racial dynamics of MoV (Dean and most of his squad mates being black) is interesting and feels progressive for it's time. Sadly, the vietnamese are not exactly depicted in the most flattering light with a rather nasty depiction of a prostitute woman as one example. The fact that Deans squad mates yell insults such as "die you rice eating motherf*ckers" and "choke on this you pukes" (gooks) doesn't make things better.
