Half-Life: Decay (singleplayer MOD) Dreamcast

[Anthony817]

I always wanted to make HLDC mods myself but never got into modding Goldsource so wouldn;t really know where to start. I do mod Battlefield 2 and a few other games on PC but those take up most of my modding time. I would love to see somebody make tutorials on how to mod it as you can still do a lot with it.
