Room Restrictions are a pre-game option controlled by the Room Moderator. When a specific Restriction is turned on, a certain type of weapon or gear cannot be used, such as Sniper Rifles and Backpacks. However, some Restrictions only allow a certain type of weapon class, like the usage of only Pistols and Sniper Rifles. These restrictions provides a challenge to players who can't do well without that class of weapon/gear.
Note: For any weapon restriction you can still use your melee weapon. The only way to have two weapon restrictions is with a Super Elite Moderator.
