Let guards have different jobs to do. Like Circle Guard, Triangle Guard, Square Guard and Head Guard. Those of the jobs cost different price for one life and permanent. Remove all normal guard skins except for "Black" or "Golden" skins("Black" and "Golden" skins is available to equip with different jobs you choose). It would be more funny if make different jobs for guards. And let guards only available to do their jobs depends on what they choose. Here is some ideas for those team:
Circle Guard: Let circle guard available to clean body, they gain extra(more) money if the "players" is still alive(let that when players down, would have chance still alive) when clean up.
Triangle Guard: Basically, you got guns to kill/shoot/terminate players that failed the games and those who disrespect Frontman. That's all.
Square Guard: Manager of the Guards. This role should be limit as 1 player only. Square Guard available to kill Guards who shoot on "Frontman" when "Frontman" as "Player" or "Guards". Square Guard would also available to kill/shoot/terminate players that failed the games. However, Square Guard would earn extra money when anothers guards(Circle Guard and Triangle Guard) do their job. Square Guard will receive a little coins bonus(For example, 15 coins for clean up and Square Guard would receive 5 coins).
Frontman: Frontman can choose between "Player" or "Guards". Frontman available to kill/terminate the Guards who annoying against him(Such as Guards shoot him or else). Frontman available to choose the games in start of the lobby. Frontman shouldn't be shoot by the Guards when "Frontman" failed the game. When "Frontman Player" failed the game, he can switch between "Player" and "Guard" freely. "Frontman Player" will automatic immune to all games(wont dead) when they failed to complete the challenges as a "Frontman Player". But, "Frontman Player" won't earn "wins" and "coins" when disguised as "Player"(when they failed). Guards shouldn't be able to shoot Frontman
