Many people seem to think that mines are useless in this game, because you need such a high engineering level to plant undetectable mines. But I found a trick to make even your least inteligent characters be able to plant perfect mines. The trick is simple: place the mine behind a door so that your enemies dont see it before they open and explode into a million pieces

Yes, it's good to remind people you can use mines to make booby-traps. They work great with other mines or with dynamite for chaining explosions too.

I find it way more fun to attack with my entire squad all at once, I have so much ammo that I don't even care.

TRRRRRRRRRRRRR
