Where Is The Impostor?

In this high stakes, 4 vs 1, Impostors vs Sniper game mode, Impostors need to blend in within the guards to survive and collect 5 coins to win before the timer runs out or they get caught by the sniper, as a sniper you need to find the spies and eliminate them before they get all 5 coins, but be careful to not run out of ammo!
