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,

It could be good see the main Chraracter be a Vietnam soldier.

This was the greatest Half-Life mod of all time. Resident Evil in Vietnam, so damn brilliant, even though I hated escorting that idiot Barney around.

So does anyone know if the guys who made Shellshock 2 Blood Trails admitted to ripping off this mod?

This is a wonderful game I still think about alot. The Napalm Edition was a good spirited but poorly executed attempt at remaking it. Before I perish from this planet, I would like to see a remake for this game that is wholly faithful to the spirit of the original that uses the modern day Source engine.

Preserving the original voice acting and only touching it for the sake of actual improvement would be key. I'd also like to rework some of the puzzles. There's plenty that could be touched up and made better. The almost impossible to kill zombies should be kept, obviously. I'm curious if the George Romero zombie in Black Ops was in any way inspired by these...

I've never made a mod or map in my life, but suddenly I'm strongly inspired to, and though I should probably start with smaller projects, I aim to ultimately tackle this ambitious one. I hope to inspire some of you good gamers/coders. I'm very happy that this original mod's affect inspired the Napalm Edition, but I think we should give another go...

Yes it was a fun game to play and make. I was one of the voice actors in the game and made models and textures too. Nathan the creator of this world is a very talented guy and I'm happy he had the vision for this game. It would be neat to try and remake this and leaving as much as possible intact (voices especially) as you mentioned.

Heart of Evil: Source. It's been done.

Well it's more of a port with some enhancements but it's better than Napalm IMO. Hell I don't mind that it's not in HD, it's more preserving of the original's feel that way (though that's just the purist in me). The gameplay makes up for lack of visual updates for what it's worth.

We don't need another remake. Just enjoy what we've got.

Yeah! Lots of features were removed on the Napalm Edition just like the "Zombie Barney Ally" and the Alien Ship as well as others.

To start of with the good things, Heart of Evil certainly is a unique mod. The Vietnam setting is a one of a kind in the long run of half-life mods. It looks as good as an half-life mod can get, with custom textures, models, weapons en effects. The game has its own voice acting, sometimes serious and sometimes just goofy. The maps looks great and because of the games length you get to do a lot of sight-seeing around the different areas of the game. The 60's fibe, the humorous natives, and little…
