This mod took over 2 years to make, contains new weapons, monsters, textures, sounds and code, making it the largest SPHL mod ever. Set in the Vietnam War, your mission is to assassinate one renegade colonel by the name of Kurtz, "with extreme prejudice". Unfortunately the only way to get to him is by wading through armies of Viet Cong and hostile US troops, not to mention hordes of the undead roaming the earth and feasting upon the flesh of the living. It's just you, Barney and your chainsaw against the world. "Think "Apocalypse Now" after Coppola is kidnapped by Rastafarian drug lords and given the full treatment. As the mod progresses, things aren't as one-dimensional as they seemed when you first accepted this mission... there's something fishy going on here, and you don't think it's the Nuoc Mâm. Rating? Five out of five." - Silver Sorrow, hangar16.com
This is one of the best Half-Life mods ever! This mod is set in the Vietnam War, and it's kinda similar to the movie "Apocalypse Now". However, it becomes much different when you will see the first zombies. Your mission is to assassinate an US Army officer called Kurtz, however you will soon notice that there is a much more complicated plot in the game. This is a total conversion: the mod uses very few resources from the original Half-Life, it has many new sounds, textures and models. You can fight your enemies with an authentic collection of Vietnam War weaponry, like the M16 and the AK-47. And you will also use a Chainsaw (excellent against zombies)! You will fight US Army Soldiers (but you will frequently encounter friendly US Mike Force soldiers), Vietcongs and zombies. You will also have a sidekick called Barney, he's really similar to the original security guard but now he packs a powerful Colt .45 with a near-perfet aim! He will be needed for special tasks like operating radios and driving vehicles. While transiting from one chapter to another, you will stay in a vehicle while Barney drives it to another location. You can order your troops to do something with some neat voice commands. Unfortunately the friendly AI can be quite dumb and can't follow you properly! You will also encounter a few medics during the game, they can be extremely useful for healing you and other soldiers especially at higher difficulty levels. The locations are really amazing, you will fight in US Military bases, vietnamese cities and villages in the jungles of Vietnam. In many maps you will encounter civilians but they are just there for scenery! You can read many documents (high entertaining value), collect items to perform some special actions although the puzzles can be VERY confusing because of the design of the maps (you will do lots of backtracking). Overall, an absolute play. Also check the remake called Heart of Evil Napalm Edition (but be sure to play this one first!).
