(aka MD Device or Little Doctor)
This weapon uses the target's own mass against itself by creating a chain reaction where the molecules try to tear themselves apart from one another. The more mass a target has, the more damage potential. The beam is hard to focus limitting its range and uses more power than a cannon.
Requires 1 point of gun power for each hex to target. Calculate to hit like a cannon but count range double. Damage is worked out like a normal cannon but the beam power drops by one for each hex of range. In addition, subtract the target ship's size from its shield level to find the 'effective shield level'. If this number is greater than 0, work out damage as normal. If this number is negative, add one more dice to the beam damage for every negative level of effective shields. If a ship explodes from being hit by this, damage done to other ships is calculated the same way (subtracting size from shield.) A chain reaction may occur.
