Traps

Some doors have plastic bombs attached to it when you start the level.You can also attach it manually from your inventory.Left : normal door, Right : door with PLASTIC BOMB!Plastic Bomb detonates when the door it's attached to is opened,and inflicts significant damage to all adjacent units to the door.Though it can be disarmed by a squad member with "Bomb Tech" skill, I think there's no need to assign your skill points as you can circumvent the bomb attached doors by destroying walls.Don't open this door by yourself, just stay away from it and let your enemy do!
