Me and a few friends of mine are working on a Half-Life 2 Source Mod set in the Half-Life universe. We have already come up with a design for the game, and we are currently working on a script. On our team we have two skilled programmers, two modelers, an artist, and some design people. We're currently looking for voice actors for this project. Here is what we're looking for. I'll put an age range for how old each character should sound. Though if you are younger or older but sound in that age range, you're a-ok.
Blink: The protagonist, we've actually given him a few short lines. This is a very easy job. We want someone without any heavy accents. He is American. Should be a strong-sounding character. Age range, 18-30 year olds.
Raptor: The leader of your squad. One of the more line-heavy roles. He is a lean British man. Very casual about certain things, though he can get serious quickly. Heavy British accent. Age range, 18-30 year olds.
Deadlock: Voiced by my Scottish friend Connor.
Rawhide: Voiced by my brother Nick.
Vortigaunts: I really have no idea on this one. If you've played Half-Life games you know what a Vortigaunt sounds like. If after some sound editing (that we can provide) you sound like a Vortigaunt, that's enough for me.. Though I don't want any heavily accented Vortigaunts, cause we know those don't exist.
Combines: This isn't very hard to do. Basically we just record you saying things in a clear voice, lower the pitch. Add in Combine sound effect beeps and boops and you're a Combine. If you want to do a voice, but you don't want anyone to hear your voice. This is the job for you.
That's all I've got for now. I'll add more requests as we add more to the script. If you'd like to try out for one or more of these jobs, send me a PM. Post in the topic if you're interested or something.
