The start to a new mod, the hardest bit, you have to stay motivated and know what to do, I would know; I made some mistakes before. Half-Life 2 Beta: Retribution used a lot of stuff from insolence, which uhm... Yeah is not the best thing to do. This time I'll do things right, thousands (maybe not that much) of original content will be made with a new story based of the beta for the mod.
At the moment I'm currently working on studying the storyline of the Half-Life 2 Beta and creating models as I go along, I have no idea how long this will take, but it will take long. There's a good chance that a good bit will be completed; but as a one man project progress will halt before it is fully completed. I am looking about getting some more team members, if you have some skill in mapping, coding, texturing or modelling contact me and please provide some of your work so I can see your skills.
Any way no matter what happens with this, I hope you enjoy the ride
