Making a comeback from Battlefield Bad Company 2, the motion detecting balls for the Recon class made an appearance in yesterday’s live stream from E3. It is unknown if the Tactical Unattended Ground Sensor, or T-UGS, from Battlefield 3 will be at the Recon’s disposal.
The Motion Sensor is a gadget utilized by the Recon class and is an integral tool for scouting and collecting real-time intelligence. This portable high-tech device is designed for sensing even the slightest twitch of movement, alerting the owner when an enemy has breached the premises on foot or by vehicle. They can be thrown much like a grenade to help spot enemy infantry and vehicles in its radius. They operate for a short period of time, after which it will no longer detect enemies.
1) Motion balls will not detect you if you stand still.
You can change the direction that you are looking at (move your mouse), but as long as you do not actually move, you will not be detected by the motion balls.
2) Recon balls are active as soon as they leave your hand
This means that if you do a far throw, the ball will scan the area near you as it travels forward.
3) A new recon ball cancels your previously thrown recon balls.
You can only have one recon ball active at a time.
4) A ball will beep if an enemy moves within its detection radius.
This holds true for both enemy and friendly balls. If you hear it beeping, it means that the recon ball is detecting an enemy. The enemy could be you if the recon ball was deployed by the enemy, meaning that you will know when you’ve been detected. The balls do not sound off on friendlies.
5) Your whole team can see active friendly recon balls and enemies detected by them.
Enemies will appear on the mini-map and on the full size map. If you’re on a hardcore server, you can hit M to bring up the full size map, and you will see detected enemies and active recon balls. Recon balls deployed by the enemy will not show up on your map.
