Noisemakers
Not knowing where your enemy is and purposely making obnoxious sounds to draw them out is fun. Knowing where your enemies are because you through a noisemaker is even better. These item can be as simple as something handheld that you could crank to make noise, or complex as a small speaker that you could through and would make small random sounds like someone walking, shooting, talking and even static. This could confuse a player and draw them out from campus because they think you’re somewhere else. This also can annoy other players surrounding the device. Throwing this into the server room while in the vents and rushing for lab would be the perfect example for this.
Some drawbacks to this are the fact that this could be so annoying that no one wants to use it other than to annoy their teammates. Other than that, some advantages are being able to trick the enemy team into thinking you’re somewhere else you’re not. Entirely confusing the enemy.
A way to place this item into the game is to place at least 2 on both sides of the map. Anywhere would be ideal as long as they are in reach within a minute or two after spawning. Office 4 (Above) is a perfect place to place this device. Inside office 4, nothing spawns which would be a great home for these devices.
