BattleMod support for Silver has been dropped since v2.5.
Back when he had BattleMod support, people were constantly complaining about him being unfair to fight despite him being one of the weakest picks after balance adjustments (Hear: Needing to use a cooldown projectile to be able to grab players, thrown monitors being unable to damage other players if they had more than 0 Def ontop of having no spinjump).
Not wanting to invest more hours balancing a character for a gamemode I don't even play myself, I decided to simply drop compatibility for BattleMod and don't feel like going through the same cycle again.
