Imagine one player acting as a stealthy "Claw" user while another causes mayhem with "Armor" and "Hammerfists."
You don't need to be a reverse engineer to push the mod forward. Here is how the community can help now:

Once connectivity works, the next challenge is keeping game state consistent across all clients.
