Discord Announcement
1. Add a new match making system, so that player can easily find other players who are online and check
their stats.
Through the new system, players are able to send duel match request and manage in-coming
challege request simultaneously.
Once a challenge request is accepted, both players would be taken into an online match.
Players can also receive challenge request while in singleplayer game.

weapon, lift them up and slam them down.
