In the last game, I've got the Ion Beam Weapon (which can disable shields) in the first sector. In this game all enemies in the 2nd sector happened to have 2 levels of shield, thus I lost on 4th due to the inability to break these shields (and no power to use Ion Weapon).
In previous games, I've never seen more than 1 ship with 2 level shields in second or even third sectors. Does it mean that the game adapts the enemies to your ship's setup?
If yes, how can I handle that? Will selling/destroying the weapons which are too powerful for the first sector help?
