We are really happy that the mod community is still very active !
You should consider renaming it, as Experimental Wars (with a 's') is already taken
We are aware of the lack of mod vault in FAF, but it's on the roadmap.
You have to understand that featured mods are for mods that propose a new gameplay experience (Nuke for the win, Labwars, Murder Party, phantom,...) or shiny news units and factions (Nomads, Wyvern, Blackops, xtremeWars,...).
We are no allowing balance mods for now.
The line between a balance mod and a new gameplay mod is thin. You can for exemple consider labwars as a balance mod where all units are removed except labs.
But as it's radically different from the basic gameplay, it has his place in the Featured mods program.
We will test and evaluate if your mod is fitting in the program. But you have to be aware that we are limiting the amount of Featured mods proposed at the same time.
