I tried to base myself as much as possible on XEN from Half Life 1 with floating platforms and such, also the way to go to the Gonarch Lair which I can also bring as a PVP map. I also updated the texture Pack putting textures and models similar to the game's XEN, new HUD without HP, now with the interface equal to when you don't have a HEV suit like in Half Life 1 in the prologue. Map comes with mods folder and Resource Pack, please have them inside Minecraft.
