360 awareness

This concept is very important, because each player must be able to get all the information (i.e.: the sound of a door opening, footsteps, an air vent breaking, hostages talking ...), understand what it means, where it comes from, and react accordingly. Such a total immersion is required since visual contact is not enough: the field of vision covers only 900 of the surrounding. Therefore each player should not listen to music, they should play this game with headphones and with a bit of training be able to aim and shoot accurately in a direction where a sound has been heard, as a reflex. For this concept to work it require you to know the map you are playing so you can match sounds with a location on the map: footsteps do not make the same sound when a player is on sand as they do on a pavement. Another set of sounds present on certain maps that you can use against your enemies, are the “sound triggers”: these are sounds (i.e.: a plane, a dog barking...) that are played when a player goes through a certain part of the map. When you are able to locate the sound on the map, a simple Look at the sonar will tell you whether the sound has been created by a teammate or an enemy. Such a skill is appreciated when you need very fast reactions based only on a sound (e.g. an enemy sneaks up to you and starts shooting at you). Use markers On certain passages, you need to break something to pass through (i.e.: an air vent, glass from a window ...), these are markers. Check their state to find out if an enemy has already breached in.
