Earlier today I was playing as TEC against 1 hard Vasari AI. Near the middle of the game, I raided several of it;s planets and noticed most of them were Military Labs.
Near the end of the game I had12 planets and he had 3. Though, he managed to fire a Kostura Cannon at several of my planets, crippling them instantly. I had raided those planets and found no Military Labs. He took 5 of my planets after using his kostura cannon and beat me. My fleet, I estimated, was nearly twice as big as his, maybe more, but he killed me with the kostura.
Do you think he managed to research the Kostura before I started destroying his Military Labs mid-game?
