Mines

[horselance]

In fact i liked the idea of damage reduction. But not 5%. It must be 25% or 30% less damage. If an air tank triggers mine, it will deal full damage to air tanks and 30% less damage to ground tanks (and ground creeps). Same goes for ground tank trigger.
Because when an air tank passes through the mine, it jumps to air and explodes there. But if a ground tank passes, it just explodes on the ground. So we wont need 2 types of mines...

In fact they are "spider mines"
