说明上说COL舰可以释放20枚相对应的机雷如下
The Gravity Cracker COL releases 20 Gravity Mines when it detonates. Please see that weapon for the damage pattern cased by a hit from a mine. Gravity Cracker COL does no damage (other than collision damage) if it strikes a ship before detonation.
The Implosion Cracker COL releases 20 Implosion Mines when it detonates. Please see that weapon for the damage pattern cased by a hit from a mine. The Implosion Cracker COL does no damage (other than collision damage) if it strikes a ship before detonation.
但如果没有研究出Gravity Mines和Implosion Mines,这种船攻击方式是怎么样的呢?还是说完全没有作用?
