I'll get to the point, as I often do not do.

Only hybrids can lay mines, and they must spend 2 bio-mass to lay one. They can only lay mines next to them, like spawning, but when the build screen comes up it is instead used to construct the mine. The mine has 6 units total but must have at least 1 computer, 1 weapon, 1 engine, and 1 shield. It cannot have spawning chambers. The mine is detonated either by the self-destruct command or a similar one, affects all titans within 1 hex of it, and does not give any points for any damage it does. It ignores shields with a 100% chance if a hit, however at max the mine can do only 3 damage per titan and then only if it has 3 weapons. It only takes 1 hit to destroy a mine. Mines cannot be landed upon by a titan, so a truncation for no visible reason will reveal your mine despite it not being seen.

The engine is to power the shield which cloaks the mine that turn from enemy eyes. Engine tech must be equal to shield tech in order to power it. (As such, 1 engine can power 2 shields at half its tech.) The shield tech is played against the computer tech of any enemy titan that can see its hex to decide if it is seen or not. When there are 2 shields, the power of the shield tech is doubled, however both shields must be powered.

The amount of computers determine the range the mine's scan range, 2 being default with one computer and +1 for every extra computer. (2 so the mine can see at 1 hex around itself.) This gives a max possible scan of 4.

Weapons determine damage, 1 per weapon. Once the weapon tech breaches a certain amount the mine damages in an area effect of 3, its own hex and up to 2 rows of hexes around it. The level of the wepon tech should probably be high for this breach to occur, encouraging a lower shield tech for easier spotting of this dangerous mine.

So, I think that covers everything. The idea came from RipSpace by the way, lol. Comments?
