The way the system is setup, you cannot have more than one Config Mod active at a time. You can look out for modders who integrate other aspects of other peoples mods into their own though. Shameless plug, I am one of those modders! Currently I have the full Biometal mod integrated into my own mod, and working on getting both the Rocket RV mod and the Greenheart Mod integrated into my own.

Can more than one mod be used? If so, what do i need to do?

You can have as many asset mods or addon mods enabled at once as you like.

Config mods are parallel to the old large-scale mods Battlezone II had that were used by launching the game with a different .cfg file (hence the name). These could only ever be activated one at a time. Due to an unfortunate change to the system that had to be made for BZCC, map packs couldn't fall under the other categories and had to be lumped in with these config mods.

I now have an All In One mod. It includes my assets, the Biometal Assets, Rockets RRV assets, and the Greenheart Assets.
