Greetings ! I'm Alley from the HLDM-Pro team.
We are currently working on this project since a few months and we're going pretty fast. Our mod adds a lot of new features to the original Half-Life such as new physics, revamped maps, gamemodes and more in progress.
You can find us here (and most informations) :

We are actually looking for a skilled animator to help us with our new animations system (9 way blended anims), please contact us if you are interested in helping us or know someone that might have some free time to help us.
Thanks TWHL, see you ingame when it's released
