rebel: This is how it worked in etqw -
Mines are no longer restricted to mineable terrain as in W:ET. It seems that the biggest mental shift people can make is that you can find mines on anything, including walls, Forward Spawns, and Objectives. They are visible and are also destroyable with anything explosive.
There are two types of mines: proximity and trip. When planting mines, you select mines (6) then can use Mouse1 (_attack) to place a Proximity Mine or Mouse2 (_altfire) to place a Trip Mine. Trip Mines are activated by an enemy tripping the beam of light and explode immediately. Proximity Mines blow up when an enemy comes close enough, but give off a little audible beep and give an enemy some warning before they go off.
Both types of mines can be destroyed by any type of explosive weaponry as well as EMP/Scramble grenades.
Even unarmed mines will explode. Throw mines onto the ground near enemy vehicles or turrets and do not arm them. Then throw a grenade at the unarmed mines and this will result in a bigger explosion which will help conserve your ammo.
So say there were 1000 mines on the objective… and the entire enemy team were shooting at your team while standing on these mines - ONE nade from you would kill the entire team. This is why people dont stand next to or on their own mines in etqw.
