HECU Radio Voice Pack

Now your X-Com soldiers can scare the crap out of those alien overlords with menacing radio chatter, from a unit that has plenty of experience dealing with E.T. infestations. Introducing the HECU Marine Radio Voice Pack, with audio lines straight from the first Half Life video game!

PREVIEW VIDEO UP AND RUNNING! Check out the mod in action!


-174 audio lines pieced together from the audio files of Half Life's most iconic human foes.
-Custom made audio lines.
-Randomised voice cues for all actions.


If you'd like to make your own HECU Radio Mod then you may do so. Half Life is a nearly 20 year-old game, so using the sound files shouldn't be an issue. However I ask that you do not redistribute or edit the contents of this particular mod without my permission. Instead, please share this mod with your friends by linking them to this page, thank you :) .

If you'd like some of your soldiers to sound like the marines from Opposing Force, I'd recommend you check out this excellent mod by Jblade: https://steamcommunity.com/sharedfiles/filedetails/?id=630487800

The screenshots also feature Capnbubs Accessories Pack http://steamcommunity.com/sharedfiles/filedetails/?id=618977388&searchtext=

as well as Uejji's Battle Rifle Pack http://steamcommunity.com/sharedfiles/filedetails/?id=739654958&searchtext=battle http://steamcommunity.com/workshop/filedetails/?id=732321325

@I SAVED STRATHOLME It works in WOTC. I'm currently using it.

Hey Beagle! I actually found them online, and didn't pull them from the game files myself. This is the link I got them from: https://www.sounds-resource.com/pc_computer/halflife/sound/1111/ Hope they work for you!

Hey Cosmic, where exactly in HL did you extract the voice files for this excellent pack from? I'm looking for them if you have an easy resource.

@Spinosaurus Aegyptiacus I don't know, I would assume it wouldn't have too much trouble as it's a voicepack. I haven't gotten WOTC yet though, so I can't tell you for sure. I'd just give it a try and see if it shows up or not.

Is this WOTC compatiable?

oh, no I haven't. I'll have a look

@ihonnyboy I did increase the tempo of all voice lines that I created in the last update, I just didn't make a video to reflect this change. Have you tried the mod out recently? It's probably not 100% accurate to Half-Life, but it is much better than any of the preview videos that are currently up.

Hey, jsut figured I'd mention this (I know it would be alot of work), but I think you're not recreating the HECU vocies 100% correct. The sentce.txt file in HL1 actually has little additional settings that change the pitch and tempo of the HECU lines, by default they'll sound very slow comapred to how they compare in game. I've already edited togather several of the orginal lines, but I have yet to edit any new lines togather. If you want I can send you the edits and show you want I'm talking about.

Thanks for the info! There is indeed one, it's a shame that is so loud compared to all the other sounds in the game that it's basically ear rape.
