Gravity Mine

The Grav Mine is a deployable Device. It can be placed on the battlefield where it will bury itself into the ground, before activating. The activated mine is completely invisible to the enemy, but it still can be destroyed if fired upon. The Mine will stay active until the end of the round.

Effect
When an enemy enters the Mine’s detection radius, it will detonate and affect all enemies within the area of effect.

The Grav Mine reduces the movement speed of enemies within the blast area.

The Mine can’t be triggered by the robot who placed it or by his allies.

Strategies
Anti-Skirmish – If you’re robot is being frequently out-maneuvered by Skirmisher-type build, try luring them into a Grav Mine trap; then, you can engage them on a more equal footing, and chances are your robot will have more Durability than your opponent’s.

Ambush – Place the Mine in narrow passageway or in front of Pick Up spawn points, then hide nearby. When an enemy springs the Grav Mine, use their slowed condition to your advantage.

Turret Setup – When your opponent is slowed, run by and deploy a Turret near him to secure maximum damage delivery.

Avoiding Pursuit – Drop the Mine in a narrow passage while being pursued by an enemy some distance behind you. Your opponent will have to stop and spend some time trying to destroy the invisible mine, hopefully buying you enough time to escape.

Up Close and Personal – Deploy the Mine in close quarters combat or near a Juggernaut-type robot. Even if your enemies see it coming, they might not have enough time or space to evade the explosion.

Combo Mines – Place both an EMP and a Grav Mine on the same spot to assure that any enemy who springs the trap will be left completely vulnerable. Alternatively, if an enemy springs up a Grav Mine, take advantage of his reduced maneuverability, run up to him and release an Anti-Robot Mine in his feet.

Counter-strategies
Avoidance – Due to their nature, Grav Mines are not dangerous if there’re no opponents around to take advantage of their effect. Therefore, if you’re sure that you’re far from any enemies, you can walk around without worry of triggering such mine. Keep in mind that if you do trigger one, however, this might leave you exposed to enemy Skirmishers and will give the enemy advantage in collecting the Pick Ups on the map.

Mine-Sweep – While it’s nearly impossible to clear mines with most weapon, the Trasher and the Sprayshot, with their 100% hit rate within a cone of effect, are perfect “minesweepers”. Just aim for a spot where you suspect a mine might be placed, such as a door threshold or a Pick Up spawn point, and fire away. These two weapons make sure to destroy any buried explosives, guaranteed. Also, all weapons that deliver area-of-effect damage (such as Missiles) are a viable, albeit more expensive alternative.

Destroy Parent – Destroying an enemy Mine-user will immediately deactivate all the Mines he has planted. If your team is being harassed by running into a lot of Mine trap, you should prioritize the enemy Mine-users in combat.
